Reasons for automatic transmission kicking when starting off:
1. Malfunction of solenoids:
* Solenoids control gear shifting.
*A faulty solenoid can cause the transmission to engage abruptly.
2. Contaminated or insufficient amount of transmission fluid:
* Transmission fluid provides the lubrication and pressure needed to change gears.
* Contaminated or insufficient fluid can cause increased friction and kicking.
3. Worn or damaged clutch packs:
* Clutch packs transfer power from the engine to the transmission.
* Worn or damaged clutch packs can cause slippage and kicking.
4. Faulty torque converter:
* The torque converter transfers power from the engine to the transmission.
*A faulty torque converter can cause vibration and kicking.
5. Mechanical problems:
* Worn or damaged gears, bearings or shafts can cause kicking.
Steps to resolve the issue:
1. Checking the level and condition of the transmission fluid:
* Check the transmission fluid level on a cold engine.
*The color and odor of the liquid may indicate contamination.
2. Diagnostics of solenoids and electronics:
*Using a code scanner may reveal faulty solenoids or electrical problems.
3. Replacing clutch packs:
* Worn or damaged clutch packs must be replaced.
4. Repair or replacement of the torque converter:
*A faulty torque converter may require repair or replacement.
5. Mechanical repair:
*Requires specialized knowledge and equipment to repair mechanical problems.
Note: Transmission kicking may be a sign of a serious problem. If you are experiencing this problem, it is highly recommended that you contact a qualified mechanic for diagnosis and repair.
