Possible causes of kicks when switching automatic transmission in Opel:
*Low Transmission Fluid (ATF): Transmission fluid provides lubrication, cooling, and hydraulic pressure to shift gears. Low ATF levels can lead to insufficient pressure and shifting problems.
* Contaminated or old transmission fluid: ATF breaks down and becomes contaminated over time, which can reduce its effectiveness and cause slipping or kicking when shifting.
* Worn or damaged transmission parts: Worn solenoids, clutches, clutches or bearings can cause the transmission to malfunction and shift rough.
*Transmission electronics problems: Sensors, electrical connectors, or the transmission control module can fail, affecting transmission performance and causing kicking.
*Faulty Throttle Position Sensor: This sensor tells the Engine Control Module (ECM) the position of the throttle valve, which helps the ECM determine the correct timing to shift gears. A faulty sensor can lead to irregular gear shifts and kicking.
*Transmission Software: The Transmission Control Module (TCM) controls gear shifts and can have software issues that can cause kicking.
Recommended actions:
* Check the level and condition of the transmission fluid. Replace fluid and filter if necessary.
* Scan the vehicle for transmission-related trouble codes.
* Inspect the transmission for worn or damaged parts.
* Check electrical connections and transmission sensors.
*Consult a qualified mechanic or an authorized Opel service center for further diagnosis and repair.
