Reasons for automatic transmission kicking when shifting gears:
Torque converter malfunction
* Wear of friction linings
* Slipping of the torque converter locking disc
* Clogged oil channels
Gearbox malfunction
* Wear of friction discs and bands
* Damage to gears
* Failure of bearings or planetary gears
Problems with automatic transmission oil
* Low or insufficient fluid levels
* Oil contamination due to friction wear or foreign particles
* Incorrect brand or viscosity of oil
Malfunction of the electronic control unit
* Errors or malfunctions in electronics
* Damage to sensors or wiring
*Software problems
Engine mount wear
* Loose or damaged mounts that cannot compensate for engine vibration
* Because of this, vibrations are transmitted to the automatic transmission, causing kicks when switching
Other reasons:
* Poor quality automatic transmission repair
* Aggressive driving style
* Towing heavy loads
* Wear of clutch parts in the torque converter
