5 Common Causes of Automatic Transmission Failure

In this article, Gartz will help you identifycommon causes of automatic transmission failure– to promptly prevent and protect your car to operate more durably.

1. Not changing the transmission oil regularly

This is Top causes of automatic transmission failureAfter a period of use, gearbox oil will be contaminated by metal shavings and impurities, significantly reducing its lubricating and cooling capabilities.

Consequence:

- Rapid wear of internal gearbox components.
- Causes gear slippage, jerking when shifting gears or even burning the gearbox.
Solution:
- Change the transmission oil periodically according to the manufacturer's recommendations (usually every 40,000–60,000 km), orUse Gartz synthetic gear oil like ATF G6, ATF G4, CVT Red, DCTF... for extended oil change intervals, optimal protection.

2. Using the wrong type of gearbox oil

- Using the wrong type of oil (for example, oil not suitable for CVT or DCT transmission) will cause the transmission to not operate properly or even cause rapid damage.

Consequence:

- Creates air bubbles, reducing lubrication.
- Increases friction and temperature inside the gearbox.
Solution:
- Choose the right type of oil for each type of gearbox:

- CVT ⇒ Gartz CVT Red, CVT Gold
- DCT ⇒ Gartz DCTF, DSG
- Regular AT ⇒Gartz ATF G6, ATF G4, 9G-HP

3. Not changing the oil filter or cleaning the radiator

Transmission oil becomes contaminated if the oil filter is not replaced periodically, or the cooler is clogged, causing the oil temperature to rise, reducing lubrication efficiency.

Consequence:

- Increased risk of gearbox overheating.
- Causes rapid oxidation of oil and loss of protective ability.
Solution:
- Maintenance of the entire gearbox system:Change filter, clean radiator, check oil level periodically.

4. Driving the wrong way

Some bad driving habits can directly affect the life of the gearbox such as:

- Shift to N when going downhill
- Shifting gears before the car comes to a complete stop
- Step on the gas hard when the car is just starting cold
- Do not use the handbrake when parking in P

 

Consequence:

- Puts stress on internal components of the gearbox.
- Reduces the precision of clutches, planetary gears and control valves.
Solution:
- Drive properly, especially with automatic transmission. Always wait for the car to come to a complete stop before shifting gears and avoid accelerating suddenly when the engine is not warm enough.

5. Transmission oil leak

Oil leaks are one of the most dangerous signs, but are often overlooked. When there is not enough oil, the transmission will not have enough pressure and lubrication, causing rapid overheating and severe wear.

Consequence:

- Burned clutch, slipping gear.
- Transmission is slow or cannot shift gears.
Solution:
- Periodically check the chassis, axle shaft, gearbox seals... to detect early signs of leakage.Add the correct type of Gartz oiland make repairs as needed.
