The 5-speed automatic transmission AW55-50SN was designed by Aisin engineers in the late 90s for front wheel drive vehicles third-party manufacturers (other than Toyota / Lexus / Scion) with an engine capacity of 2 to 3 liters. Designed for torque up to 330 N/m.

The AW 55-50SN has incorporated many new technologies to improve dynamic characteristics, comfort and ecology of the car. One of them is the use of linear solenoids (Solenoid Linear) for soft shifting. It is this solenoid (SL) that makes the changeover seamless and virtually lossless in power flow. Another innovation is the torque converter lock-up slip mode, which uses new graphite materials. The torque converter lockup began to be switched on by the SLU linear solenoid already from the second speed (in the gas to the floor mode), without waiting for slow acceleration with the help of the turbine wheels. Ultimately, this leads to rapid wear friction lining of the torque converter and along the chain there are problems with the valve body (kicks, jolts, freezes, etc.).

In 2003, Aisin developed a modification with the code AW 55-51SN with an improved valve body for four-wheel drive vehicles.

It is better to repair the valve body with cleaning as early as possible in order to prevent a typical and fatal problem - wear of the valve block body. Depending on the condition, a decision is made on the advisability of restoring or replacing with a new one. In this valve body, the plungers are made of Teflon and practically do not wear out. The body itself is worn out, moreover, several valves are critically worn out at once, which greatly complicates the diagnosis and repair.

The mechanical part is quite reliable, but if there are any problems with it, then the planetary gear sets, the C1 / C2 drum, oil seals, bushings and, less often, the sun gear, and the mandatory repair of the torque converter are replaced.

Generally reliable box, if you don’t fry on it regularly, if you ran 200 thousand km and don’t kick, you can generally conclude that they didn’t fly by car.

Since 2004, Aisin Warner has been producing a 6-speed automatic transmission TF80-SC for Ford, Mazda, Land Rover, Peugeot, Citroen, Opel, Saab and Volvo. The TF-80SC series of boxes is designed for torque from 100 N / m lj 420 N / m, it is mainly used for cars with an engine capacity of up to 3 liters, and only the S80 and XC90 are equipped with their own reinforced for engine capacity of 4 liters. The main differences are in the mechanical part, bag sizes and body.

Aisin also released a similar TF81-SC gearbox that handles up to 450 Nm of torque and is installed in Ford, Mazda and Land Rover. It differs in the number of solenoids, package sizes (as well as steels and clutches in them).

The main task facing the designers, in addition to increasing the number of gears, was to increase the dynamics of acceleration and efficiency, reduce fuel consumption and have a compact layout (the dimensions should be the same as those of mechanics). In this unit, Aisin first applied an innovation: shift quality solenoids that work only during speed shifts, equalizing the speeds of the shafts and making the shift imperceptible (without jerks). The same is almost the same as for preselective checkpoints. The weight of the unit has also decreased (compared to the 5-speed).

The most modern graphite materials for the friction linings of the torque converter were selected, the programs in the automatic transmission control unit were regulated by manufacturers in such a way as not to allow the driver to overheat the automatic transmission in the heat and at the same time accelerate the car as quickly as possible, etc. In the first years after release, these programs were constantly updated, eliminating the "childhood diseases" of the first years of release.

Like previous automatic transmissions, the headache is the work of the torque converter - main generator heat in the gearbox. The torque converter uses only one friction lining to lock the clutch when Jatco, ZF, etc. have long been putting on such units a basket of 2-3 full-fledged friction disc without saving space and increasing reliability.

The automatic transmission control unit program allows the driver to extremely load the transmission, forcing it to work by slipping the torque converter clutch and, starting from third gear, directly transfer torque from the engine and switch to neutral at each convenient occasion to save fuel even more and not overheat the ATF.

The usual repair consists in repairing the torque converter (mandatory), the valve body (or replacing it in a particularly neglected case), all gaskets, pistons, friction clutches, steels and an oil filter.

The TF-80SC uses a new generation oil and the manufacturer declares that it does not change. But it's like usual marketing ploy, it is definitely better than atf previous generation. But new super oil still cannot remove the suspension from friction clutches and steels, therefore, as a result, after they clog the channels of the valve block, oil starvation, which also leads to the destruction of the mechanics (for example, the oil pump will fail one of the first, the direct drum 4-5-6 speeds, the clutch package with thrust bearing, brake band, etc.).

Also, after about 100 thousand km, maintenance should be paid attention to oil leaks (seals). Having missed the level, you can roll the box at a time. These are not condo 4-mortars from the mid-90s.

The first off-road station wagon Volvo named Cross Country(in some XC markets), entered production in 1997. It was a station wagon variant of the V70, which was a facelifted 1992 850 series. He became the first big Volvo with the engine laid transversely and the drive, mainly on the front axle. Until front-wheel drive was offered only in the 440, 460 and 480 series models, technically related to Renault and manufactured in Holland.

The second generation of the wagon model off-road already called the XC70. The basis for it was the V70, created on the basis of the first generation S80 sedan. In 2007, Volvo offered the third generation XC70, based on the second generation S80.

In the development process, the XC70 has been further improved on the already high level security. The car received the second generation of WHIPS head restraints, the only drawback which - lack of height adjustment.

For the first time, child seats with two heights were integrated into the rear sofa. The lower position is for children 115 to 140 cm tall and weighing 22 to 36 kg. Top position Designed for children from 95 to 120 cm tall and weighing from 15 to 25 kg.

Why choose the XC70 over the classic V70? For example, due to a slightly different appearance or expected operating conditions. Thanks to the high ground clearance 210 mm do not have to be afraid dirt roads. For more difficult conditions vehicle is not intended.

Engines

The most widespread diesel units. D5 and D4 have 5 cylinders and a volume of 2.4 liters, but differ in power (185 and 163 hp) and environmental class. Differences are found in the bowels of the engine. The weaker one was usually called 2.4D.

Under the D3 marking, the volume of 1984 cm3 and 163 hp is hidden. It was installed exclusively on front-wheel drive versions.

Since 2010, the D5 has been offering 205 hp. Here, the manufacturer installed a pair of turbines that come into operation in series. In 2011, the engine power increased to 215 hp.

Achilles' heel of the 5-cylinder 2.4 D5 with a return of 185 hp – air swirling system intake manifold. It includes: an electric motor, traction and a set of dampers. A task this device air distribution for optimal engine performance, especially at high speeds.

Wear out over time plastic parts damper actuator, play appears, and the system starts to work with errors. For example, in the process of dynamic overtaking on high speeds with the accelerator pedal fully depressed, the resulting acceleration is less than expected. With more smooth operation the gas pedal without sudden acceleration of such hitches does not occur. Another symptom is oil leaks from under the valve covers. Luckily, the dampers don't get into the engine.

Traction wear is a less burdensome financial nuisance, only about 300 rubles. But, unfortunately, more often you have to change the entire system. The cost will include: components - about 9,000 rubles, replacement work - about 6-7 thousand rubles, system calibration - about 1,000 rubles. Total, on average, 16-17 thousand rubles.

This system was installed until 2009. After the turbodiesel began to comply with the Euro-5 standard, and swirl flaps were no longer used. Instead, a particulate filter was installed.

Whirring when starting a cold engine does not mean that the starter has expired. This is how it works air damper. The Swedes in vain used plastic gears in it. Gradually becoming dirty damper begins to block the plastic gears. As a result, the teeth do not withstand and are destroyed. Unfortunately, throttle valve it is expensive - about 23,000 rubles. The work will pull another 3,000 rubles.

Continuous noise and squealing from under the hood of the Volvo XC70 indicates belt wear mounted units. Worse if the belt will break. Then the efforts on the steering wheel will increase, the air conditioner will turn off, and the signal lamps on the dashboard. Even worse, if a broken belt gets under the pulleys. Then, like most engines, the valves can meet the pistons and it's over. The cost of restoration repairs will depend on the degree of damage and will amount to at least several tens of thousands of rubles. Later, Volvo engineers enlarged the cover, thereby eliminating the possibility of belt residue getting under the pulleys.

All problems with the drive belt of mounted units lie in design flaws tensioner. Already after 30-40 thousand km tension roller deviates from the axis and works at an angle. Soon the outer edge of the belt begins to wear out. It doesn't take long for the belt to break. So it is better to replace the belt (about 1,800 rubles) with a tensioner (about 3,700 rubles) immediately (work is about 1,500 rubles), as soon as signs of wear appear. The total cost of repairs will be about 7000 rubles.

The upper seal on the timing side is usually to blame for oil leakage from 2.4 D5. The sealant costs a penny, but about 5,000 rubles will be asked for work.

If the engine does not start, then the EGR valve is probably stuck in such a position that traffic fumes find no way out. Acute power shortage is a symptom of EGR problems. If the electronic part of the EGR does not show any signs of life, then the engine will probably need a new valve for 22,000 rubles, plus the work of a mechanic - about 5,000 rubles. If the electronics work, then the valve is probably just clogged with deposits. The cost of the cleaning procedure is about 4000 rubles.

The assets of the model include petrol units. One of them is a 3.2-liter naturally aspirated in-line six. It's incredible, but the previous release did not have six-cylinder engines.

The 3.2-liter Si6 unit has a very interesting CPS (Cam Profile Switching) technology that allows you to change the course intake valves by changing the profiles of the camshaft cams. There are two levels for this - depending on the load on the engine and speed.

In order to comparatively long engine nestled between wheel arches, it was necessary to change the layout attachments: generator, air conditioning compressor and power steering pump. The solution was called READ, and the equipment was placed above the gearbox, i.e. With opposite side usual location. There was also a timing drive, which combines a chain and a toothed belt.

Atmospheric Si6 - interesting, but not popular. He has a big appetite, which does not match the dynamics. The 3.0-liter T6 turbo engine is much more interesting in terms of dynamics, and fuel consumption is not much higher. At the end of 2013, a 4-cylinder 2.0 T5 was offered. He is more loaded than T6, and lacks character.

Gearboxes

The engines were combined with either a 6-speed manual transmission M66 or a 6-speed automatic TF-80SC (Aisin AWF21).

Twitching during deceleration in a car with a gun indicates that it is time to prepare for expenses. The same thing will be prompted by delays or jolts when trying to accelerate sharply after pressing the gas pedal to failure - “kick down”. This is due to wear of the friction discs or valve body failure. A complete overhaul of the box will cost almost 80,000 rubles, of which about 10,000 is work. A restored box costs about 180-200 thousand rubles. And all because Volvo does not recommend the production regular replacement oils in a box. All you have to do is change transmission fluid in the machine every 60,000 km (5000-6000 rubles), and there will be no problems with the box.

Volvo XC70 not old bmw, but rear axle sometimes it makes noise. His inner bearing can howl after 70,000 km. Repairs won't be cheap. new bridge costs more than 100,000 rubles, and used - about 30-40 thousand rubles. Most XC70 owners choose a cheaper solution - repairs (8-10 thousand rubles).

Chassis

Suspension - forte this model. There is an improvement over its predecessor. The first complaints appear only after 200-250 thousand km due to wear of the silent blocks of the transverse levers in the front suspension. Two silent blocks cost about 5-6 thousand rubles, replacement work is a little cheaper. After that, it is necessary to carry out work on adjusting the wheel alignment - about another 2,500 rubles. In the end, your wallet will feel better by about 12,000 rubles.

If, however, the instability of the rear of the car begins to be felt when cornering, then, of course, the problem is in the silent blocks trailing arm rear suspension.

Four-C electronically controlled shock absorbers were available for an additional fee, allowing you to choose between three levels of suspension stiffness - comfort, sport and advanced. True, after a while, shock absorbers can fail. The original rack will cost 60,000 rubles.

Can get noisy over time wheel bearings front wheels.

The Volvo XC70 is a relatively heavy model and not designed for off-road use. Some drivers forget about this. As a result, the repair of the viscous coupling may require about 9,000 rubles, and the mechanic will ask for another 2,500 rubles for the work. Total 11,500 rubles for entertainment outside the asphalt.

The large mass of the Volvo XC70 contributes to the rapid wear of the front brake pads. They have to be changed after 30,000 km of run. And that's with normal driving style. A set of new pads will cost 4,000 rubles, and the work of replacing them will cost about 1,700 rubles.

Other problems and malfunctions

Sometimes the air conditioner compressor starts to make noise. When replacing it, the pulleys and belt system should be changed. If repairs are delayed, metal fragments may enter the air circuit, so the system will have to be flushed. This means additional repair costs.

If the wipers suddenly stop obeying, this is a sure sign that their electric motor has been drowned. Water gets inside through a leaky housing and disables the electric motor and electronic module. The cost of a new electric motor assembly with a module is almost 13,000 rubles. About 2,000 rubles more will be asked for a replacement.

XC70 wiring harnesses are weaker than older ones Volvo models. However, as in other brands of cars. The situation when the insulation looks flawless, but inside the copper core is broken, is observed regularly. This leads to malfunctions or complete failure of the electronics. Restoring the contact line by adding a new electrical wire is cheaper, complete replacement electrical harness. The cost of such a procedure is from 1000 rubles and more ...

Sometimes the central electronic module CEM begins to act up.

Conclusion

In the 2013 TUV reliability report, the Volvo V70 (the XC70 is its all-terrain interpretation) was considered in the 4-x-5 category. summer cars. Of the 121 cars on the list, he took only 108th position, sharing it with Alfa Romeo 147. Average mileage vehicles in this category - about 114,000 km. Other SUVs and crossovers were better. According to DEKRA, the Volvo S80, V70 and XC70 in the category "mileage 50-100 thousand km" earned a good rating, and in the "mileage 100-150 thousand km" - excellent. This is a very good result.

Volvo XC70 is a very comfortable car, especially in winter conditions. Gasoline engines cause practically no problems. In Europe, versions with diesel engines. Besides, most widespread received a sluggish automatic transmission. mechanical box transmission is more reliable.

Advantages:

Comfort suspension

Good sound insulation

Reliable and efficient all-wheel drive

Strong suspension

Highly good protection against corrosion

Interior materials are resistant to wear

High security

The Swedish brand Volvo is considered one of the leaders in European automotive industry. Produced under this brand passenger cars regularly get into the tops of the most reliable and safe models. Yes, and car owners usually do not complain about frequent breakdowns- after all, at correct operation"Swedes" serve really for a long time and do not create problems for the owners.

But even at reliable brand there are weak points, and Volvo traditionally considers the gearbox to be such. This does not mean that the transmissions on Swedish cars break down regularly, but Volvo owners should pay Special attention transmission. This also applies to the operation and maintenance of cars.

Types of automatic transmission "Volvo"

Today, all cars of the Swedish brand are equipped with several types of popular boxes:

• AW55-50SN- five-speed automatic Japanese made that has gone through many modifications. Installed on models C30, C70, S40, S60, S80, XC90. popular model, which is in demand by many global automakers. Over the years of production and refinement, many malfunctions have been eliminated, but weak point the unit has always been considered a valve body;
• AW55-51SN- modification previous model"automatic" with a modified hydraulic unit. This version of the box was intended for cars with all-wheel drive, it was received by the Volvo S40-S70 models;
• TF80SC- six-speed Japanese automatic, installed on C30, C70, S60, S80, XC60, XC70, XC90. Modern machine, intended for powerful machines front and all wheel drive.

Typical breakdowns of automatic transmission "Volvo"

Most often, the following elements fail in vending machines on Swedish cars:

• hydroblock - the most vulnerable spot all automatic transmissions. It has a certain service life, and any breakdown is almost certainly a replacement for a new or completely sorted used valve body;
• torque converter is another common problem, especially relevant for diesel cars. The torque converter can be repaired, but only if a breakdown is immediately identified. Otherwise, the failure of the transformer will lead to damage oil pump- as a result, the entire unit will have to be changed;
• differential - malfunctions in its operation can be caused mechanical wear individual elements - bearings, gear teeth, splines.

It is important to understand that the resource automatic transmissions can be produced in different ways and does not depend directly on the mileage. Much more important is the driving style and the number of gear changes. To maximize the life of the box, you must follow the manufacturer's recommendations and drive calmly and measuredly, without slipping and sudden accelerations.

No less important is proper care behind the car. First of all, you need to undergo regular computer diagnostics - modern systems electronic sensors allow you to identify any malfunction at an early stage. To prolong the service life, you should change the oil regularly, and, if necessary, expendable materials- seals, gaskets.

If you find any oddities in the operation of the box, you should immediately contact the service for diagnostics - any delay can lead to serious consequences and significantly increase the cost of future repairs.

The first signs of transmission problems may be:

• extraneous noises - clanging, knocking, hum;
• jerks, jerks, slippage when switching speeds;
• sinking of individual gears;
• stopping shortly after the start of movement or refusal of the car to move;

Specialists of the network of car services "YAUZA MOTORS" in Moscow will carry out any complexity!

Typical malfunctions of automatic transmission Volvo XC70

A characteristic problem of all AISIN gearboxes is the valve body. The valves, channels, the hydraulic part itself, and of course the solenoids are most susceptible to wear. To date, we successfully repair hydraulic units and give a guarantee for our work.

TF80SC transmission valve body. The malfunction of which is expressed in strong blows, slipping between gears.

Undoubtedly declared 100-150 thousand km, the car drove off flawlessly, but then problems began, due to which automatic transmission repair Volvo XC70 it is undesirable to postpone, because this will lead to a further chain reaction throughout the unit. Common symptoms of mechanical problems include:

• slippage in 3rd gear;
• bumps when switching modes D and R;
• jerks when switching 1-2 and 4-5,
• emergency mode;

Oil pump automatic transmission XC70 - cranked the bushing, the car is not moving

The reason for this is worn valves hydroblock and solenoids, weak bushings of the sun gear, planetary gear and automatic transmission oil pump. In the TF80SC, pistons suffer, and in 90% of cases they are subject to mandatory replacement. It does not do without the maintenance of the torque converter.

Why us? During our practice, we have repaired more than 300 automatic transmissions AW55 and TF80. You can see examples of our work, as well as visit pages on social networks where photo reports are posted on each of our repairs (section About us), we do not take numbers out of our heads, see for yourself.

We can safely say that we have a huge experience. Moreover, for the most accurate diagnosis of valve bodies and solenoids, we use a professional hydro stand KINERGO, which has no analogues.

Examples of our Volvo automatic transmission repairs

Automatic transmission repair Volvo XC70 (AW55-51)

The work of the hands and minds of Swedish engineering, namely Volvo XC70 2006 year of manufacture, equipped with automatic transmission - AW 55-51SN.

I would like to write that the car came to us under its own power, but not this time. They brought the car on a rope (Taking this opportunity, we remind you that it is highly not recommended to tow cars equipped with an automatic gearbox). Under its own power, the car did not go to either D or R, as if the gearbox was in neutral.

Of block errors were: Two torque converter errors, and third gear slip.

After computer diagnostics, the car immediately fell into the hands of our masters, and the removal of the unit for troubleshooting and repair began, troubleshooting, as always, was not in vain and revealed a whole bunch of faults, namely: 4th and 5th gear clutch pack burnt out , faulty automatic transmission brake band and turned bushing of the automatic transmission pump .

There was a lot of "dirt" in the gearbox housing due to the destroyed gearbox parts, which worsened the condition of the still living spare parts in the box, so we always advise you to change the oil and consumables in your automatic transmissions and RKPs in a timely manner.

Repair this car the mobile took us a couple of days, as always, all the spare parts were found by us in short time, the client received the most loyal price tag and complete satisfaction from the repair in our company. The turnkey cost was 79.000 rubles considering all work.

You can be convinced of the quality of our work by visiting our service yourself, according to statistics, 98% of our customers are satisfied and recommend us to their friends! And we really try to confirm our reputation with knowledge and deeds.

Automatic transmission repair Volvo XC90 (TF80SC)

This Volvo car came to us in emergency mode, computer diagnostics showed errors in slipping 2 gears, what to do in this case? Of course, to carry out an analysis of the checkpoint with a complete and detailed troubleshooting.

Yes, we want to remind you that this car automatic transmission installed TF-80SC. Which is a 6-stage development of the Aisin concern.

And so, we will continue the analysis of this automatic transmission .. during the analysis, we saw a lot of interesting things:

One of the reasons incorrect work The automatic transmission had a planetary gear set, in which play was traced, and appearance you can imagine its state:

Friction and steel discs, of course, also burned out ..

A set of pistons and bronze bushings also required replacement:

Also, unfortunately, we had to restore the valve body, as it suffered from wear products, for this we use the original Sonnax repair kit.

As a result of such a repair, we can say with confidence that problems with the automatic transmission are no longer terrible ..

Valve body repair, automatic transmission Volvo S60 (AW55-50)

Today we are visiting Volvo S60, mileage 146.000km.

Problem: The automatic transmission kicks from 2-3, 2-1, and there is also a bump when shifting to "R".

In this car, the automatic transmission has already undergone repairs and, as we wrote, we are not the first to redo it after someone's "hands". Taking a sample of the oil found that it is quite normal, it was decided to repair the valve body.

After repairing and cleaning the valve body, carrying out adaptation and a test drive, the car drove like new, thereby delighting the owner and us with the work done.

The complex of works on the repair of the valve body cost the owner 34 000 rubles

Automatic transmission repair Volvo XC90 (4T65E)

Hello friends, finished the repair of the box 4T65E on the Volvo XC90 Let us tell you how it was!

4T65E - 4 step automatic from GM for Volvo, which they began to produce already in 1993, it’s quite a working unit that runs without problems for the first 5 7 8 years of the car’s life, in terms of the popularity of repairs in Russia, it is slightly inferior to the 5le40e gearbox that was installed on BMW cars

This time a car with a 2.9-liter engine came to us under its own power, but with slippage in all gears, especially when cold! The warm car behaved a little better, but still far from ideal.

They took a sample of oil that was black and had a clear smell of burning, later they carried out computer diagnostics, which revealed errors in slipping 2 gears, and mode R.

This was a sufficient reason to remove the automatic transmission from the car and carry out troubleshooting.

Troubleshooting, in turn, showed the true state of the automatic transmission, namely, burnt brake bands, clutches, and almost everything needed to be replaced, the verdict was one, a major overhaul!

We carried out a major overhaul of this automatic transmission, replaced the clutches, gasket kits, consumables, brake bands, and ensured that the car continued its life without problems with the automatic transmission.

Repair KP Powershift Volvo S60 (MPS6)

Volvo S60 with gearbox PowerShift DCT450- according to our new tradition Let's take a mini tour of this checkpoint.

So DCT450(WD version Wet Dual Clutch With wet clutch), manufactured by Getrag, this is a gearbox with two clutches, the scheme of its operation is that two clutches, in turn, connect different shafts, choosing desired gear(1-3-5) and (2-4-6).

And let's talk about the problems of this car in more detail. The car arrived to us with errors, namely:
- Fork failure (B)

As it was assumed that there was a mechanical failure of the plug itself, but when removing the gearbox and troubleshooting, it turned out that the error (malfunction of the plug B) appeared due to mechanical failure clutch damper, as a result, the chips fell on the forks and formed "hedgehogs", as a result of which the mechatronics did not receive accurate information about the position of the fork, and therefore "complained" about its malfunction.

In this case, the client chose the path of replacement with used spare parts, unfortunately we cannot guarantee the condition of such spare parts, but we can always provide a guarantee for the replacement work performed.

Automatic transmission repair Volvo S80 (TF80)

Volvo S80 car, with gearbox TF80.

Came with a slip of 3-4 gears, a problem with the K2 piston, yes, like on our popular ones Skoda Octavia, the reason is that the TF 80 gearbox has a similar design with the 09G gearbox.

Children's sores are almost the same as its predecessor, the entire interior suffers from burnt oil in this situation, including the brake band, which often needs to be replaced during a major overhaul, clutch combustion problems are also not caused quality oil and most importantly, piston breakdowns, due to which the car starts to slip

Changed piston kit, friction disc kit, gasket kits, brake band, sun gear as well as automatic transmission oil and filter.

Now the car does not slip, well, except for the wheels, at the start, the 3.2 engine begs for it :))

Automatic transmission leak repair Volvo S60 (AW55-50)

Hello friends! Yes, we not only repair the boxes but also change the parts that are "next" this time Volvo arrived with symptoms of a leak from the "box".

By the way, the box is a 5-mortar Aisin AW55-50, which, we want to note, is very reliable!

With in-depth diagnostics, it was revealed that the leak was from the gearbox oil seal, from the crankshaft rear oil seal, and also from the servo piston, or rather its seal.

Replaced were:

-Rear crankshaft oil seal
-Gearbox seal
- Seal for brake band servo piston.

The car left pleasant memories of its condition and well-groomed, and we, in turn, helped to maintain its good condition!

Automatic transmission repair Volvo S60 (AW55-50)

In the photo you can see the case when, as they say, no luck!

The car was produced in 2001, the owner tried to maintain the condition of this Volvo in the proper form, but no one is immune from problems with the automatic transmission, especially with the AW55 ...

Replaced:
-Clutch drums
- Planetary gear
-Brake bands
- Friction and steel discs

Served: hydroblock and hydrotransformer.
Restored box from sooo deplorable state!

The owner came to us to repair the box, there were a number of slip errors, they immediately started troubleshooting, the oil, as is usually the case on burnt automatic transmissions, was black.

Dismantled the box, saw the "meat".

The rubber seal of the piston cracked, as a result of slippage and shock loads, problems with iron began, namely:

Volvo XC70 cars were equipped automatic boxes Aisin Warner TF81SC gears.

These boxes were also installed on many other cars. For example, for some Ford models, Mazda, Land Rover, Alfa Romeo and Fiat.

The article will describe characteristic faults Automatic transmission and valve body of the Volvo XC70, as well as repair features in a specialized technical center.

Typical breakdowns that require repair of the automatic transmission Volvo XC70

In general, the TF81SC box turned out to be quite successful and, with proper care, worked out 200-300 thousand kilometers without problems before the first major repair. However, in practice, automatic transmissions are often found, which departed only 150-200 thousand, and which already require major repairs.

There are several reasons when an early repair of the Volvo XC70 automatic transmission becomes necessary.

REFERENCE. According to the manufacturer's instructions transmission oil in the TF81SC automatic transmission is designed for the entire service life, that is, up to overhaul. But, as practice has shown, changing the oil and filter, contrary to the instructions of the manufacturer, significantly increases the resource of the box.

These factors, as well as processes natural wear and tear, lead to wear of the following automatic transmission components and parts:

ATTENTION! All these components fail in the Volvo XC70 automatic transmission under normal operating conditions closer to 200 thousand kilometers.

Because of what it may be necessary to repair the valve body of the automatic transmission Volvo XC70

The valve body on the car in question belongs to the category of difficult to repair, especially when serious malfunctions occur. Consider the main problems of valve bodies Volvo XC70.

REFERENCE. Valve bodies for automatic transmission Volvo cars The XC70 was equipped with different software versions in different years of production. Therefore, the service life, typical malfunctions, and, accordingly, the complexity of repairing the Volvo XC70 automatic transmission as a whole, largely depend on the valve body operation algorithms embedded in the electronics.
