Possible reasons:
1. Low transmission fluid level:
* Check the automatic transmission fluid level using the dipstick. It should be between the ‘cold’ and ‘hot’ marks.
* If the level is below the ‘cold’ mark, add the appropriate type of fluid recommended in the owner’s manual.
2. Contaminated or old transmission fluid:
* Over time, transmission fluid loses its lubricating and cooling properties.
* Replace transmission fluid and filter according to the maintenance schedule.
3. Faulty solenoid or sensor:
* Solenoids and sensors control gear shifting and fluid flow in the automatic transmission.
* Have your vehicle inspected by a dealer or qualified workshop to determine any faulty components.
4. Friction disc slippage:
* Friction discs transfer power from the engine to the transmission.
*If the discs are worn or damaged, they may slip, causing kicks when shifting gears.
5. Valve unit malfunction:
* The valve body distributes transmission fluid through various channels in the automatic transmission to control gear shifting.
* If the valve body is faulty, it can affect the fluid pressure and cause kicking.
6. Faulty Transmission Control Unit (TCU):
* The TCU is the computer that controls the automatic transmission.
*If the TCU is faulty, it may result in incorrect shifting and kicking.
7. Mechanical faults:
*In rare cases, kicking may indicate more serious mechanical problems such as worn planetary gears or differential.
Required actions:
* Check the level and condition of the transmission fluid.
* Replace fluid and filter if necessary.
* Perform diagnostics to identify any faulty components.
* Eliminate any problems identified by replacing faulty parts or repairing transmissions.
