Common causes of automatic transmission failure:
*Lack of Maintenance: Regular maintenance (changing fluid, filters and seals) is critical to extending transmission life.
*Overheating: Excessive loads, towing heavy loads, or driving in traffic jams can cause transmission parts to overheat and weaken.
* Wear: Over time, parts such as gears, clutches and bearings wear out, which can lead to gear shifting and other problems.
*Mechanical Faults: Defective components such as solenoids, sensors or servos can cause the transmission to malfunction.
*Low or contaminated fluid: Low or contaminated automatic transmission fluid can cause insufficient cooling and lubrication, leading to wear and failure.
*Electronic control unit (ECU) malfunction: The ECU controls all transmission functions and malfunctions may result in malfunction or failure.
* Excessive clutch wear: Clutches used to change gears can wear out and slip, leading to slippage and other problems.
* Poor operating habits: Habits such as sudden acceleration, braking, or unauthorized towing can place additional stress on the transmission and shorten its life.
* Manufacturing Defects: Although rare, manufacturing defects can cause the transmission to fail shortly after use.
*Accidents or collisions: Impacts or collisions may damage the transmission housing or internal components.
