What are the common faults and causes of automatic transmissions?

[LeFelicity]

Common faults and causes of automatic transmissions are as follows: Oil leakage: Oil seeps from the transmission housing or oil pan, which can be caused by aging seals leading to poor sealing, or manufacturing defects resulting in pinholes in the housing. Engine stalling when engaging gear: When shifting into D or R, the engine stalls. This fault may be caused by a damaged lock-up solenoid valve or a stuck lock-up control valve. Gear lock: Incorrect input or output signals from the transmission, or issues with components or wiring, can cause this. Sometimes, communication problems between the transmission computer and other system computers may also lead to this issue. No response when engaging gear: After shifting into D or R and releasing the brake, the vehicle does not move. This is often due to damage to the input shaft or reverse clutch, or failure of the D/R brake.
