Possible causes of automatic transmission kicks and jolts when shifting gears:
Mechanical problems:
* Friction discs are worn out or jammed
* Faulty shift solenoids
* Clogged oil channels
* Torque converter problems
* Gearbox shaft wear
Electrical problems:
* Malfunction of rotation speed or temperature sensors
* Damage to wiring harness
* Malfunction of the electronic control unit (ECU) of the automatic transmission
Automatic transmission fluid:
*Low fluid level
* Insufficient fluid pressure
* Fluid contamination or aging
Other reasons:
* Incorrect shift cable adjustment
* Wear of engine or gearbox mounts
* Clogged automatic transmission radiator
* Malfunction of the automatic transmission oil pump
Diagnostics and repair:
To diagnose the cause of kicking when shifting an automatic transmission, you must perform the following steps:
* Check the level and condition of the automatic transmission fluid
* Read fault codes using a scanner
* Check automatic transmission fluid pressure
* Inspect the mechanical components of the automatic transmission
* Check electrical wiring and automatic transmission sensors
Depending on the diagnostic results, repairs may include:
* Replacement of friction discs, solenoids or other mechanical components
* Torque converter repair
* Replacement of automatic transmission fluid and oil filter
* Reprogramming the automatic transmission ECU
* Troubleshooting wiring or sensors
Attention: Delay in repairing automatic transmission kicks and jolts can lead to serious damage to the transmission. It is recommended that you contact a qualified mechanic for prompt diagnosis and repair.
