Mechanical problems
*Clutch Slip: Clutch slippage can cause delayed shifting, jerking and reduced transmission efficiency.
* Damage to Shafts and Gears: Damage to these components can result in noise, vibration and inability to shift gears.
* Oil Pump Damage: A faulty oil pump can cause loss of oil pressure and damage to the transmission.
* Damaged differential: A damaged differential can cause noise, vibration and reduced traction.
Electrical faults
* Faulty Solenoids: The solenoids control the hydraulic valves that change gears. A faulty solenoid can result in shifting errors, jerking and loss of power.
* Malfunction of speed sensors: Speed sensors send information about the speed of rotation of the shafts and wheels to the automatic transmission ECU. A faulty sensor can lead to incorrect gear shifts and other problems.
* Automatic transmission ECU malfunction: The automatic transmission ECU controls the operation of the transmission. A faulty ECU can lead to a variety of problems, including shift errors, overheating, and transmission failure.
Oil and filter problems
* Contaminated or old oil: Contaminated oil can reduce lubrication and cause premature wear of transmission components.
* Clogged Oil Filter: A clogged filter can restrict oil flow and cause shifting problems and other problems.
Other faults
* Oil Leaks: Oil leaks can cause low oil levels, which can damage the transmission.
* Overheating: Overheating the automatic transmission can damage transmission components.
* Worn clutches: Worn clutches can reduce the efficiency of torque transmission and lead to jerking and slipping.
