Causes of kicks when switching automatic transmission modes:
Mechanical problems:
* Worn clutches: The clutches responsible for shifting gears can wear out over time, causing kicking.
* Contaminated Transmission Oil: Dirty or old oil can prevent smooth shifting.
* Torque Converter Problems: A faulty torque converter can create additional pressure, causing jerking.
* Stuck Solenoid: A stuck solenoid can cause the transmission to shift incorrectly.
Electrical problems:
*Wiring Problems: Damaged or worn wiring can interfere with the sensors and solenoids that control gear shifting.
*Faulty Automatic Transmission Control Module: A faulty transmission control module can produce incorrect signals to the transmission, causing kicking.
Software problems:
*Outdated software: Outdated software may contain bugs that cause rough shifting.
* Incorrect setting: An incorrectly configured automatic transmission control module can cause kicking.
Other possible reasons:
*Low transmission oil level: Insufficient oil level can cause oil starvation and kicking.
* Incorrect type of transmission oil: Using the wrong type of transmission oil may affect transmission viscosity and shifting characteristics.
* Worn Engine Mount Rubber: Worn engine mount rubber can allow the engine to move more, causing kicking when shifting gears.
If you experience kicks when switching automatic transmission modes, it is recommended to contact a car service center to diagnose and troubleshoot problems.
