Despite the absence of factory regulations for replacing the contents of automatic transmissions, many Ku Seven owners are guided by the instructions of ZF-Getriebe GmbH, which produces automatic transmissions 0AT and 8HP55. The company's recommendation is as follows: the service life of the automatic transmission fluid is unlimited, but when the transmission operates with increased loads(frequent driving with or without a trailer at speeds close to the limit, aggressive driving with sudden acceleration and braking), it must be changed after a run of 80-120 thousand km, or every 8-10 years.

Prevention and diagnosis

If you listened to our recommendations regarding service automatic transmissions, we will be glad to see you in our network. Our specialists will help you choose the right consumables for the liquid and a set of related consumables, and will also expertly replace them, completely or partially.

Spare parts

To avoid incompatibility problems different compositions at partial method updates, you need to choose transmission fluid, similar to the Audi Q7 already in the box. You can select the necessary components for using the VIN code.

If the waste is completely drained, that is, not only from the crankcase, but also from the torque converter, the brand of transmission can be changed.

In addition to G055162A2 oils, other oils were poured into the 0AT(ZF) automatic machines at the factory (they differ in code, color and characteristics). You will also need:

1. sealing gasket - 0AT321371,
2. filter - 0AT325429,
3. traffic jams:

• for drain - 018321377B (seal included),
• for level and fill control - 01V321376 (with o-ring - 01V321379).

Original oil for gearbox 09D (AISIN) - G055025A2.

Codes for other spare parts:

1. pan gaskets - 09D321371,
2. oil filter - 09D325435
3. drain plug - WHT000206A, and its gaskets - 09D321181B
4. filler/control plug - WHT000323A, plus seals - 09D321379,
5. You may need magnets - 09D321368.

To pump in a fresh transmission, a special pump is used: VAG 1924.

The mileage of the Audi Q7 is 155 thousand kilometers, the car is seven years old. This is not the first time this car has come to us. Did Maintenance, the suspension was repaired. The reason for today's appeal is Change oil in automatic transmission. This procedure will take a little over an hour. Let's begin.

The car is already on the lift. While the mechanic receives everything necessary to change the automatic transmission oil, we will check the suspension again and assess the condition brake system. Let's take a look under the hood. Recommendations: replacement brake discs and pads all around. Plus - replacement drive belt with rollers.

For automatic transmission oil changes You need more than just oil. Many car owners are surprised by this fact. Let me explain. When changing the automatic transmission oil, the filter is changed. To change the filter, the automatic transmission pan will be removed. This means that new bushings and gaskets are needed, filler plug. Original spare parts are expensive. Therefore we offer high-quality analogues. For example, Mayle. Excellent manufacturer. Bushings, gasket and filter for Meyle automatic transmission are cheaper, almost twice as expensive. But the quality is the same. With automatic transmission oil it is more difficult. It's better to fill original oil , 9 liters. An analogue will also work; ZF “boxes” are installed on many machines. Transmission BMW oils 7045E, VW/Audi G-055-025-AZ – as an option.

You can order any original spare parts for Audi repairs, as well as their analogues, by calling +7 (812) 770-67-44

Let's describe the process automatic transmission oil changes. Unscrew the drain plug and drain the oil. Then fasten the automatic transmission pan. Carefully remove the tray and wash it. We change the automatic transmission filter and pan gasket. We install the pallet. The oil is “filled” using a special installation. You can use a regular “syringe”; it holds 500 grams – that’s a long time. “Installation” is much faster. All that remains is to start the engine and check the oil level. Changing the automatic transmission oil We recommend doing the Audi Q7 every 50 thousand kilometers.

Changing the oil in the Audi Q7 gearbox is most often associated with the repair of the automatic transmission itself, or it is replaced with a new one during work to eliminate oil leaks, since it must be drained to carry out the work. Automatic transmission oil is filled by the manufacturer once for the entire service life of the vehicle. It is recommended to entrust changing the oil in an Audi Q7 automatic transmission to professionals, but in some cases you can handle this operation on your own.

Functions ATF oils in automatic transmission Audi Q7:

• effective lubrication of rubbing surfaces and mechanisms;
• reduction of mechanical load on components;
• heat removal;
• removal of microparticles formed due to corrosion or wear of parts.

The color of the ATF oil for the Audi Q7 automatic transmission allows you not only to distinguish between oil types, but also helps to find out in the event of a leak, from which system the fluid escaped. For example, oil in automatic transmission and power steering has a red tint, antifreeze is green, and oil in the engine is yellowish.

• wear of automatic transmission seals;
• wear of the shaft surfaces, the appearance of a gap between the shaft and the sealing element;
• wear of the automatic transmission sealing element and the speedometer drive shaft;
• backlash input shaft automatic transmission;
• damage to the sealing layer in the connections between automatic transmission parts: pan, automatic transmission housing, crankcase, clutch housing;
• loosening the bolts that connect the above automatic transmission parts;

Low oil level in the Audi Q7 automatic transmission is the main reason for clutch failure. Due to low fluid pressure, the clutches do not press well against the steel discs and do not contact each other tightly enough.

As a result, the friction linings in the Audi Q7 automatic transmission become very hot, charred and destroyed, significantly contaminating the oil. Due to lack of oil or low quality oil

• in automatic transmission Audi Q7:
• the plungers and channels of the valve body become clogged with mechanical particles, which leads to a shortage of oil in the bags and provokes wear of the bushing, rubbing parts of the pump, etc.; overheat and wear out quickly steel wheels
• gearboxes;
• rubber-coated pistons, thrust discs, clutch drum, etc. overheat and burn;

The valve body wears out and becomes unusable. Contaminated automatic transmission oil cannot fully remove heat and provide high-quality lubricant details, which leads to various malfunctions
Automatic transmission Audi Q7. Heavily contaminated oil is an abrasive suspension, which under high pressure creates a sandblasting effect. Intense impact on the valve body leads to thinning of its walls at the locations of the control valves, which can result in numerous leaks.

You can check the oil level in the Audi Q7 automatic transmission using a dipstick. The oil dipstick has two pairs of marks - the upper pair Max and Min allows you to determine the level on hot oil, the lower pair - on cold oil. Using a dipstick it is easy to check the condition of the oil: you need to drop some oil onto a clean white cloth. When choosing an Audi Q7 automatic transmission oil for replacement, you should be guided by a simple principle: it is best to use oil recommended by Audi. Moreover, instead of

mineral oil You can fill in semi-synthetic or synthetic, but in no case should you use oil of a “lower class” than the prescribed one. and is designed for a very long period of use of the Audi Q7. But we must not forget about the appearance of mechanical suspension as a result of wear of the clutches over a very significant mileage. If the automatic transmission has been operated for some time in conditions of insufficient oil, it is necessary to check the degree of contamination and, if necessary, replace it.

Methods for changing the oil in an Audi Q7 automatic transmission:

• Partial oil change in the Audi Q7 gearbox;
• Complete oil change in the Audi Q7 gearbox;

A partial oil change in an Audi Q7 automatic transmission can be done independently. To do this, just unscrew the drain on the pan, drive the car onto an overpass, and collect the oil in a container. Usually up to 25-40% of the volume leaks out, the remaining 60-75% remains in the torque converter, that is, in fact this is an update, not a replacement. To update the oil in the Audi Q7 automatic transmission to the maximum in this way, 2-3 changes will be required.

A complete oil change of the Audi Q7 automatic transmission is carried out using an automatic transmission oil change unit, car service specialists. In this case you will need more oil ATF, which is what the Audi Q7 automatic transmission holds. For flushing, one and a half or double volume of fresh ATF is required. The cost will be more expensive partial replacement, and not every car service provides such a service.
Partial replacement of ATF oil in an Audi Q7 automatic transmission according to a simplified scheme:

1. Unscrew the drain plug and drain the old ATF oil;
2. We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is treated along the contour with sealant.
3. We gain access to the automatic transmission filter; it is advisable to change it at every oil change, or rinse it.
4. At the bottom of the tray there are magnets, which are necessary for collecting metal dust and shavings.
5. We clean the magnets and rinse the tray, wipe it dry.
6. We install the automatic transmission filter in place.
7. We install the automatic transmission pan in place, replacing the automatic transmission pan gasket if necessary.
8. We tighten the drain plug, replacing the drain plug gasket for the automatic transmission.

We fill the oil through the technological filler hole (where the automatic transmission dipstick is located), using the dipstick we control the oil level in the automatic transmission when it is cold. After replacing the oil in an automatic transmission, it is important to check its level after driving 10-20 km, already with the automatic transmission warmed up. If necessary, top up to level. The regularity of oil changes depends not only on the mileage, but also on the nature of driving the Audi Q7. You should focus not on the recommended mileage, but on the degree of contamination of the oil, systematically checking it.

I also replaced a little in my AISIN 09D automatic transmission.
To keep things in order, I also replaced the oil in the front and rear gearboxes and in the transfer case. Mileage 80,000 km

Material:

1) Mobil 3309 automatic transmission oil took 16 liters, ( filling volume with removal of the pan and filter 7-8 liters, changed in two passes. Replaced it with removal, drove 1000 km, replaced it again with removal)

2) rings, gaskets and sealing ring filters - new

3) oil for transfer case Mobil "ATF LT 71141", 1 l

4) Castrol gear oil "Syntrax Universal Plus 75W-90", 3l

5) At first, the automatic transmission filter was not the original one, for the first 1000 km, then I installed the original one.

6) don’t forget about the sealant for the transfer bolts, there are no rings there

The process is not complicated:

Drain the slurry from rear gearbox, there are no magnets there, fill it to the edge.
First we unscrew the drain, then the filler.

Then we perform a similar procedure with the front gearbox

Next in line is the automatic transmission, drain it through drainer what has drained, remove the pan, there is still about 700 ml of oil and unscrew the filter. reassemble in reverse order, install new gaskets, seals and rings

The photo shows that there are small chips on the magnets, which is absolutely normal for a mileage of 80,000 km. clean the pan, magnets, wipe the installation contour of the gasket, lubricate it a little with oil and put it in place.

This is what a clean pan looks like, you can wash it with gasoline

Here in the photo is the filler and drain plugs Automatic transmission, larger filler, which has a smaller drain.

I think there is no point in writing about setting the oil level in an automatic transmission; there is a lot of information on the forum. From the main one, it is set with the engine running in position “P” at an automatic transmission temperature of 40 degrees Celsius. After a short test drive, it makes sense to check the level again.

Yes, here’s another point: if you’ve already crawled under the car and are tinkering with the gearbox, it makes sense to check the automatic transmission wiring plugs for the presence of oxide, oil, dirt in them, to prevent the possibility of poor contact.

The oil was clean everywhere, without traces or smells of “crime”, in the main gears and transfer case it was possible to wait for 100,000 t.km and then change it, but I didn’t buy a new car, I didn’t want to get it unpleasant surprises, I feel calmer when I know where I have what is filled, installed, in what condition, etc.

And there is one more point pushing for the replacement of fuels and lubricants in aggregate units, this point is determined by the lifespan lubricants and preservation of their properties. The car is almost 5 years old; the shelf life or even storage life of “civilian” oils is limited to 5 years.

After replacing the fluids in the transmission and after an adaptation period, I didn’t notice any obvious changes, “well, probably” it shifts more smoothly, “well, probably” it’s easier to roll, but this is all subjective and in the subconscious I want to believe in it)))

Replacing these fluids is a preventive measure - it allows you to prolong and make the life of the units easier, again with regularity of this service with an interval of 60-80 t.km, if there are obvious problems with the automatic transmission, then changing the fluid is unlikely to cure them....

From advice - if the mileage is more than 150 thousand km. and there was no automatic transmission oil change and you still decided to replace it, it is better to do it in two stages, the first time without removing the pan - drain through the drain bolt what has drained and add a new one through the filler. And the second time, after 1000 km, with the removal of the pan and replacement of filters.
