The car of the American corporation General Motors Chevrolet Cobalt is produced with both an automatic gearbox and standard mechanics.

This article will tell you in detail about which units are installed on this vehicle, as well as about possible malfunctions and actions if they are detected.

What boxes are installed on Chevrolet Cobalt

In the case of using an automatic transmission, we are talking about a conventional six-speed gearbox found in many cars. It should be noted that this unit has the ability to manually shift gears, which is sometimes necessary.

If we talk about mechanics, then a two-shaft gearbox with five forward gears and one reverse gear is installed on the Chevrolet Cobalt. The design feature is the presence of a synchronizer in all forward gears.

Fuel consumption is a question asked by many car owners. It is no secret that the use of a certain unit significantly affects the amount of fuel consumed by a vehicle during operation.

Below is a table that shows the approximate consumption in the case of using automatic transmission and manual transmission according to the manufacturer's data.

According to the table, we can conclude that the mechanics consumes less fuel compared to the automatic transmission, but this is not too big a minus in the case of automatic transmission. In addition, it should be noted that these indicators change depending on the operating conditions of the vehicle. For example, in suburban conditions, the car will consume less fuel.

It should be noted that according to many reviews of the owners of the Chevrolet Cobalt, in fact, it consumes more fuel per 100 km. Real fuel consumption with quiet driving and mixed mode (city + highway) is 8 liters in the case of a manual transmission and 9.2 liters with an automatic transmission.

Typical problems

Often during the operation of the car, various breakdowns occur, and the Chevrolet Cobalt is no exception. It is worth noting that often malfunctions are found in the operation of the gearboxes installed in the car.

Automatic transmission malfunctions

The automatic transmission used in the Chevrolet Cobalt is considered a fairly reliable unit, and the only most likely transmission failure can occur as a result of frequent slipping of the car. So, for example, if the owner starts abruptly, he will soon need to repair the automatic transmission.

Also, this can be attributed to the negligence in the operation of the box in the cold season and the unwillingness to warm up the engine before starting the unit.

The second most common failure occurs in the solenoids. This happens as a result of wear and tear of structural elements, and can lead to failure of the gearbox.

Manual transmission malfunctions

If we talk about common breakdowns in a manual transmission, then these should include:

• oil leakage;

• wear of structural elements;
• difficult gear shifting.

Among the likely signs that will report a breakdown, they note the presence of extraneous noise, knocking out a gear, the inability to engage a certain gear while the car is moving.

Replacement and repair

In the event of a breakdown of the operated transmission, the owner of the Chevrolet Cobalt should contact a service station for repair as soon as possible. The service station employees will not only repair or replace structural elements of the automatic transmission or manual transmission in a short time, but also diagnose the vehicle and identify the cause of the breakdown.

It is not recommended to repair the unit on your own, since the lack of at least minimal knowledge about the device of the box and the principle of its operation can lead to additional breakdowns in the operation of the device.

Thus, the option - to seek help from professionals - is more profitable than trying to repair the checkpoint with your own hands, despite the fact that you will have to spend more money.

Checkpoint cost

As for the cost of gearboxes, then:

• The new automatic transmission will cost the owner 50-60 thousand rubles, and the used version will cost 30-45 thousand rubles.
• A new manual transmission will cost about 40-50 thousand rubles, and a used unit will cost from 25 thousand rubles.

Therefore, if you need to carry out a complete replacement of the automatic transmission or manual transmission design, it is worthwhile to prepare the funds in advance.

Change of oil

Despite the need to visit the service station in the event of a breakdown, the owner of the Chevrolet Cobalt can do it with his own hands, both in the manual transmission and in the automatic transmission. To do this, you need to stock up on the necessary tools, a container for draining the old oil, as well as a syringe or tube with a funnel in order to fill in new oil.

After all the materials are prepared, you can start the main process.

Oil change in automatic transmission

Before talking about the oil change procedure, it is worth clarifying a few points that will affect the safety of the work:

• Replacement is best done on a flyover or inspection pit.
• It is recommended to turn off the engine before starting work.
• Do not fill in a liquid with a viscosity that differs from the recommended one as a new oil.

For the last point, it is worth adding that a special regulation prescribes what the viscosity of the oil used should be. As for the replacement itself, the car owner will need:

• Place the car on an overpass or pit. In addition, raise its front with a jack and place wheel chocks under the wheels.
• Unscrew the drain valve plug and place a prepared container under the hole.
• Wait for the oil to drain.
• Unscrew the pan holder and remove the container for cleaning. It is necessary to clean it from the remaining excess oil, as well as from magnetic shavings and other similar contaminants.
• Replace transmission oil filter.
• Install the pan and filter in place, while replacing the gasket.

• Screw on the drain valve cap and pull out the filler plug.
• Fill in the required amount of new oil.
• Reinsert the dipstick.

After the oil change has been carried out, it will take a short time to start the car engine so that the fluid warms up and is distributed throughout the entire transmission structure. Only then can the vehicle be used again.

Oil change in manual transmission

Changing the oil in a manual transmission is a two-step process. First of all, you will need to drain the old oil and only then start filling the new one. The sequence of actions for each stage is shown below.

• In order to drain the oil, the car owner needs to install the car on the inspection hole and raise it with a jack. Additionally, you can install stops under the wheels.
• After the position of the car is fixed, you can start draining the oil. To do this, you will need to dismantle the engine protection and install a previously prepared container for old oil under the gearbox crater. To drain it, you must unscrew the drain hole fixing cap. The oil will pour out.

• The next step is to clean the transmission pan. To do this, it will need to be pulled out by removing the mounting bolts using special tools. It is necessary to clean it from oil that did not have time to leak out, as well as from magnetic shavings.
• After the box pan is cleaned, you can start filling with new oil. To do this, using a wrench, you will need to unscrew the filler plug and use a syringe.
• When the oil is filled to the required volume, all that remains is to tighten the lid and assemble the car structure in the reverse order.

The end of the procedure will be to warm up the oil by turning on the engine for a quarter of an hour. If necessary, oil can be topped up using the same sequence as above.

The operation of the Chevrolet Cobalt requires a careful attitude of the owner, and this is especially true for the transmissions used in the car.

Automatic transmission oil is a working fluid. Its condition is important not only for the operation of automatic transmission units, but also for the engine and the entire car as a whole. An oil change in a Chevrolet Cobalt automatic transmission can be full or partial. Partial replacement involves draining the oil naturally through the unscrewed sump plug (sometimes you need to remove the entire sump of the automatic transmission crankcase, depending on the car model). With this method, 30-40% of the oil changes, the rest remains in the automatic transmission mechanisms.

It changes during regular service. A complete oil change in a Chevrolet Cobalt automatic transmission is carried out on special equipment in a service station. In this case, the installation hose is connected to the automatic transmission cooling radiator and the oil is squeezed out under pressure. The frequency of oil change in the Chevrolet Cobalt automatic transmission, recommended by the manufacturer, is 15-20 thousand km for a partial change and 50-60 thousand km for a complete one. But these terms are highly dependent on the operating conditions of the car /

The cost of changing the oil in a Chevrolet Cobalt automatic transmission:

At increased loads, aggressive driving style, car operation in extreme conditions, if the car is idle in traffic jams every day, it is recommended to do a complete oil change every 25 thousand km. With a complete replacement at service stations of St. Petersburg services, the condition of the automatic transmission is checked by suspensions in the used oil.

They also wash the pan, clean reusable filters, change the oil pan gasket. Disposable filters are replaced. The cost of changing the oil in a Chevrolet Cobalt automatic transmission depends on the type of replacement, the make of the car, whether the customer buys little in the service or came with his own, etc.

It is important to keep an eye on the oil level of your vehicle. If its quantity is insufficient and if it is excessive, the subsequent repair of the automatic transmission is provided. The oil level is checked with a special dipstick or sensor. In addition to the oil level, you also need to monitor its purity - dirty oil is darker than the original one due to suspended particles in it.

Gear oils differ in their characteristics. It is very important that the grade of the filled oil corresponds to that recommended by the manufacturer. Also, mixing different oils is not allowed. For example, you bought a used car and do not know what kind of oil is in the automatic transmission. Then it is better to make a complete oil change of the Chevrolet Cobalt automatic transmission in our service.

Competent oil change in automatic transmission Chevrolet Cobalt

Maintenance of the gearbox and replacement of the transmission fluid in the Chevrolet Cobalt automatic transmission at an affordable price

Why change the oil in a Chevrolet Cobalt automatic transmission?

Many car enthusiasts believe that there is no need to change the oil in an automatic transmission - there is a legend that the manufacturer pumps a high-quality fluid into them, which is enough for the entire mileage of the car. But this is not the case. Experienced motorists and mechanics agree that regular replacement is still necessary, since during the operation of the box, its teeth, gears, clutches and discs wear out, pieces of metal fall into the crankcase, get stuck between rotating parts and wear out the assembly.

Aggressive driving and overheating of the box lead to the appearance of soot and burning in the automatic transmission, which also does not add "health" to it. With temperature drops, condensate forms in it, which dilutes the oil, and as a result, it loses its characteristics. If you are the owner of a Chevrolet Cobalt, then the oil in the automatic gearbox should be changed regularly - this will extend its trouble-free operation several times.

Note that often the cost of repairing an automatic transmission is half the price of a new box, so many drivers simply change the unit without doing any repairs. But the price of an automatic transmission is quite high, so it is wiser to change the oil in the Cobalt automatic transmission in Moscow in time than to restore it after a breakdown.

When is the oil change in the Chevrolet Cobalt automatic transmission performed?

There is no exact recommended figure, as manufacturers indicate different values ​​for different types of machines. But professional car enthusiasts recommend changing the oil in the automatic transmission in the Chevrolet Cobalt after a run of 50-60 thousand kilometers if the car was operated under normal conditions or after 30-50 thousand if the driver prefers dynamic driving, top speeds and sharp braking (or the car is operated in severe frosts).

How does a full and partial oil change in a Chevrolet Cobalt automatic box take place?

There are two main ways to change the transmission fluid:

1. Independently in the garage if there is a pit.
2. In a professional service station on a lift and with the use of special equipment.

Some drivers, deciding to save a few hundred rubles, change the oil in the garage. But this is a controversial decision, since it is impossible to completely drain it (the sediment remains in the crankcase and on the clutches). There is a partial oil change in the Chevrolet Cobalt automatic transmission, which does not correct the situation with pollution. Sometimes drivers fill in fresh oil for the second and third time, try to flush the box with special means, but this is economically unreasonable.

Do-it-yourself oil change in a Chevrolet Cobalt automatic transmission is performed only at a partial level. In the process, up to 60-80% of the lubricant is drained, however, this is sufficient to prevent wear of the transmission and its parts. The procedure is extremely simple and allows independent replacement without contacting specialists.

Functions of oil in automatic transmission in a car

The main purpose of the oil in the gearbox is to provide lubrication for the components and parts involved. Along with this, others are also distinguished function lubricating fluid:

• heat removal during prolonged engine operation;
• reducing the load and increasing the resource for the development of parts and components;
• removal from the working mechanisms of particles formed as a result of friction and wear of parts.

The most common reason for changing the oil in an automatic transmission on a Chevrolet Cobalt is a leak and a decrease in its level. This is due to the wear of the oil seals, gaskets, gaskets, shaft surfaces. Also, the reason may be loose connections or lack of sealant.

Due to leakage and a decrease in the oil level, the friction of the mechanisms and transmission units increases. Further signs that pay attention to are the following:

• incorrect operation of the gearbox, lack of switching or its inconsistency;
• extraneous sounds, twitching or noises;
• slip when shifting, increased engine speed.

Experts emphasize that one should not wait for such signs. They indicate not only the need to change the oil, but also the relevance of the overhaul of the transmission. This question should be addressed only to highly qualified specialists.

Taking into account this factor, preventive check of the condition of the lubricating fluid becomes important. To do this, drip it onto a clean rag or napkin. The color determines the need for replacement, the darker it is and the more impurities, the worse for the transmission.

Also pay attention to the burnt smell. This may be associated with wear of parts, overheating of the gearbox, the end of the shelf life of the lubricant itself. When a similar symptom manifests itself, replacement is also required.

How to independently change the oil in an automatic transmission in a Chevrolet Cobalt (2013)?

However, experts emphasize that in Russian conditions, it is necessary to change the lubricant every 60 thousand kilometers. This indicator is due to the specifics of domestic roads, temperature extremes and environmental conditions.

Independently, without special equipment, the car owner can only make a partial oil change, draining up to 60-80% of the fluid. To do this, he will need:

• a clean, lint-free rag or rag, rubber gloves;
• a set of screwdrivers and keys, a knob with attachments, a probe for measuring;
• container for drained grease;
• new lubricant, funnel and filling hose;
• replacement parts - filter, gasket, gaskets and other parts as needed.

When changing the oil, pay attention to safety engineering... The high temperature of the lubricant drained after the engine warms up is emphasized. To avoid burns, it is recommended to be careful when unscrewing the plugs and removing the pallet.

They also emit the toxicity of transmission lubricant. All manipulations are best done with rubber gloves. If the mixture comes into contact with the skin, it is washed with plenty of clean water.

At the preparatory stage, you will need to warm up the car, the best option is a short trip of 5-10 km. Then the car is parked out of the blue, if possible, use an overpass, a repair pit or a lift.

In the absence of such, a jack and supports are used to raise the car evenly. On a Chevrolet Cobalt automatic transmission, oil change is carried out with the removal and flushing of the sump, so space is needed to work from below.

Draining old oil and flushing the sump with removal of chips

The procedure for an independent oil change in an automatic transmission for Chevrolet Cobalt implies the following stages:

• a container is substituted under the drain, unscrew the cork;

• the old oil is drained from the pallet in the Chevrolet Cobalt automatic transmission when it is removed; for this, the retaining fasteners are unscrewed;
• replace the filter, check and, if necessary, change the gaskets and seals;
• the pallet and magnets are cleaned and wiped dry, the condition of the transmission parts is assessed by the amount of metal shavings;
• return the pallet to its place, plug the drain plug.

During the oil change process, the system is also inspected for faults and leaks. Any worn parts should be replaced to avoid early breakdowns. If a lot of impurities are found in the grease being drained or there are a lot of chips on the magnets, they turn to the service station for a full diagnosis and repair of the automatic transmission.

Filling new oil in automatic transmission

The oil change in the Cobalt automatic transmission is carried out in two stages. After draining the spent liquid, the system is restored to its original form. Then new grease is poured into the transmission filler neck.

An important aspect is the volume of the lubricant poured in - the same amount is required as was drained. For the calculation, use a measuring canister or commensurate containers. At the same time, attention is paid to the temperature difference in volumes, due to which the drained lubricant is given time to cool down.

After filling with a dipstick, check the oil level in the transmission; it should not be below the minimum value. Then the engine is warmed up, if possible - by a short trip with all gears shifting. After that, the lubricant level is checked again - in a heated state, it should not exceed the maximum value.

A few days later, the poured oil is drained as waste and proceeds to the second stage. Experts do not indicate the exact mileage for this, some car owners repeat the replacement after 10 or 100 km, others after a thousand. The procedure is preserved; after the second filling, the oil change procedure is considered complete. Further, for preventive purposes, it is recommended to periodically measure its level in the system.

Chevrolet Cobalt is a compact golf class car, originally created for the American market. The 2004 model had a sporty image and was equipped with powerful engines. For example, the top-end versions of the first generation Cobalt had 2.0 turbo engines with a capacity of 200-260 horsepower. Sales were discontinued in 2010, and the second generation Cobalt premiered a year later. The eponymous budget sedan was not available for the United States, but it was supplied to Russia. The car was equipped with a 1.5-liter engine with a capacity of 105 liters. with., which worked with manual transmission or automatic transmission. Sales continued until 2015, when the car was renamed Ravon R4.

Automatic transmission oil change schedule

According to the recommendations of experienced motorists and specialists, the frequency of oil change in the Chevrolet Cobalt automatic transmission is 60-100 thousand km. Below are examples of negative climatic factors, as well as driver errors, in which the automatic transmission oil change schedule will have to be reduced by two or three times.

• The driver violates traffic rules, starts abruptly and brakes, actively rebuilds and makes instant maneuvers without any need
• The gearbox overheats due to frequent shifting, which can be caused by active operation in urban conditions, where there are many traffic lights. In this situation, the beneficial properties of the oil are lost faster.
• Regular vehicle operation off-road (stones, sand, gravel, snow), as well as in rainy and slushy weather, in extremely high or low ambient temperatures
• Towing cargo and driving at maximum speeds above cruising

Signs of untimely oil change in automatic transmission

• The oil pressure in the line drops, which is caused by a low oil level in the automatic transmission, a malfunction of the oil pump discharge valve, as well as contamination of the solenoids or valve body with wear products
• Slipping when shifting gears
• The movement is impossible, despite the complete serviceability of the gearbox.

• Original - GM Original Dexron VI
• Alternative - Shell, Mobile, Valvoline
