The easiest way is to change the oil at a service station, a service center or any other organization engaged in the maintenance and repair of vehicles.
If it becomes necessary to do it yourself, there is no need to be afraid - everything is feasible.
Oil change in manual transmission for Chevrolet Cobalt
Step-by-step instructions on how to change the transmission fluid in the Chevrolet Cobalt manual transmission:
- remove protection power unit engine;
- under the box crankcase we place a pallet with a volume of at least two liters;
- using a 9.5 wrench, unscrew the drain plug;
- we drain the old slurry;
- put the plug back;
- remove the control hole plug with a key;
- fill in new oil with a syringe to the lower edge of the hole;
- we return the plug and protection of the power unit back.
It is best to change it immediately after the trip, when it has not yet had time to thicken. In case of heavy contamination, the presence of a large amount of clots and mechanical impurities, it is recommended before pouring a fresh portion.
For this, fluids with low viscosity or special cleaning agents are used. Thus, if you follow the instructions, even on your own it is not so difficult to do it.
Another question arises: is it necessary to do this at all?
Do I need to change the oil in the manual transmission?
The automaker claims that the oil filled in mechanical box, - for the entire service life of the unit.
However, situations arise when you have to change it:
- the transmission was repaired;
- the car is operated in a climate where the winter temperature drops below minus 30 degrees Celsius;
- the operation of the transmission has deteriorated.
Checking the level and quality of oil in manual transmission
The oil in the manual transmission must be filled to the lower level of the control hole or to the upper mark on the dipstick.
If it is flooded below, this will lead to box malfunctions, if it is higher, it will leak. The level should be checked when the car is in a horizontal position - on a platform or suspended from a lift.
You can determine the quality of a substance by appearance... It is a clear oily liquid without clots and mechanical impurities. The color of the liquid depends on the manufacturer and may vary. If during the check it is found that it has turned black, thickened, a sediment has appeared, then it is better to change it.
What kind of oil to fill in a manual transmission Chevrolet Cobalt
To top up, you need to know what kind of oil has been poured into the Cobalt transmission. It is generally mineral, with an SAE 75W-85. This viscosity grade is oriented towards temperate climates and is not suitable for severe frosts.
Residents of the northern regions are better off changing it to synthetics with a viscosity grade of 75W-90 any reliable brand... The transmission is produced by all the same brands that produce motor lubricants.
How much does the replacement cost
Car service change transmission fluid for Chevrolet, Cobalt costs from 450 rubles, plus the price of the substance itself and additional manipulations. If you change it yourself, then the price of the issue will be equal only to the cost of the substance. A liter of transmission fluid from popular brands will cost from 400 to 800 rubles.
Oil change in automatic transmission on Chevrolet Cobalt
The replacement principle is similar to the manual transmission replacement procedure:
Replacement scheme:
- we put the car on a pit or overpass;
- warm up the engine;
- remove protection;
- we drain the old slurry through the cork;
- we return the cork to its place;
- change the oil in the automatic transmission through the hole in the engine compartment;
- we return everything to its place.
If there is a lot of liquid, it can be drained through the side control hole.
Do I need to change the oil in the automatic transmission?
It is required to change the oil in the Cobalt automatic transmission in the same cases as in the manual transmission - if the transmission has been repaired, if the car is operated in a cold climate, if the substance has ceased to cope with its duties.
Checking the level and quality of oil in automatic transmission
Monitor the level and quality transmission oil in the automatic transmission of Cobalt, you can use the probe. It is poured to the level of the lower edge of the side control hole. Excess liquid can be drained through it. However, one must understand that it is much more difficult to drain the excess than to top up. Therefore, the replacement procedure is carried out carefully, adding liquid in small portions.
Automatic transmission oil type
Initially, in a modification with an automatic machine, "mineral water" from GM with the same viscosity class as on mechanics - SAE 75W-85 is poured. You can replace it with either a mineral or synthetic product with a similar SAE or 75W-90, 80W-90 of any brand you like. The main thing is that the Dexron VI specification is present.
Partial or complete oil change in automatic transmission
In the automatic Cobalt box, both partial and complete replacement of the transmission fluid is possible.
Partial
This is exactly what you can do at home. Self-draining through the bottom hole can not drain all, but only about two-thirds. If there are 8 liters of fluid in the car, only 5 of them are drained.
Full
This method is possible only in a car service with special equipment - a displacement apparatus, which, using pressure, removes all the old fluid from the system.
The effect of a complete replacement far outweighs the effect of a home procedure. It is recommended to do it in urgent need, when serious problems in operation. And for the prevention of malfunctions, it is enough and partial.
How much does an automatic transmission oil change cost?
A partial replacement in a Chevrolet Cobalt automatic transmission in a car service will cost the same amount as on a mechanic. But the full cost is already from 1000 rubles and above. Additional costs will be required for flushing or replacing the filter. The cost of consumables is from 400-500 rubles per liter. It should be noted that with a partial replacement, approximately 5 liters will be required, and with a full one - all eight.
Do-it-yourself oil change in a Chevrolet Cobalt automatic transmission is performed only at a partial level. In the process, it is drained up to 60-80% lubricating fluid however, this is sufficient to prevent wear on 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, there are others. function lubricating fluid:
- heat removal at long work engine;
- 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.
Most common reason oil change in automatic transmission on a Chevrolet Cobalt - 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 revs engine.
Experts emphasize that one should not wait for such signs. They indicate not only the need for an oil change, but also the relevance overhaul transmissions. With such a question, you should contact only highly qualified specialists.
Taking into account this factor, preventive check of the condition of the lubricating fluid becomes important. To do this, it is dripped 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 conditions. the environment.
Independently, without special equipment, the car owner can only make partial replacement oils, draining up to 60-80% of the liquid. 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.
On preparatory stage you need to warm up the car, the best option a short trip of 5-10 km is considered. 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 the 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;
- draining the old oil from the pallet in the automatic transmission Chevrolet cobalt it is performed 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, clog 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 power of 200-260 Horse power... Sales were discontinued in 2010, and the second generation Cobalt premiered a year later. Eponymous budget sedan was not available to 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 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 two to 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 temperatures the environment
- Cargo towing and driving maximum speeds above cruising
Signs of untimely oil change in automatic transmission
- The oil pressure in the line drops, which is caused by low level oil 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
An automatic transmission is one of the most complex and expensive parts of a car. In order for the automatic transmission of the Chevrolet Cobalt to function normally and serve for a long time, you need to regularly carry it out Maintenance and change the oil, which is an important component of the automatic transmission.
Gearbox oil is used not only as lubricant for moving elements, but also as a working fluid for hydraulic system control and torque converter. In addition, it removes excess heat from heating parts, therefore normal work automatic transmission is impossible without it.
Over time, the oil loses its properties. This adversely affects the vehicle's handling and accelerates the wear of individual transmission elements. Timely replacement oil facilitates gear shifting of the Chevrolet Cobalt gearbox and significantly extends the service life of the box.
When to change the oil in the automatic transmission
At normal conditions When operating a car, change the oil in the automatic transmission for the Chevrolet Cobalt every 60-90 thousand kilometers, depending on the type and model of the gearbox. However, there are factors that adversely affect the oil, thereby reducing its service life:
- aggressive driving style with fast start and hard braking;
- unfavorable climatic conditions, including sharp changes in ambient temperatures;
- use of the machine mainly in urban conditions;
- excess permissible weight;
- using a trailer and transporting heavy loads;
- frequent off-road and mountainous terrain.
These factors reduce the oil change interval in automatic transmissions by about 30%.

The car of the American corporation General Motors Chevrolet Cobalt is produced both with automatic transmission gear shifting and with 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 to be taken if found.
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 consume 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 expense fuel 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 operation of 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. Service station employees not only in short time repair or replace structural elements of the automatic transmission or manual transmission, 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, owner of Chevrolet Cobalt with its own hands can carry out an oil change both in a manual transmission and in an automatic transmission. To do this, you need to stock up the right 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 oil filter gearboxes.
- 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 structure of the entire transmission. 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 need to unscrew the fastening cover drain hole... 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 caring attitude of the owner, and this is especially true for the transmissions used in the car.
