Reasons for automatic transmission kicking in Toyota Corolla:

1. Malfunction of solenoids:
* Worn solenoids may result in incorrect gear shifting.

2. Low transmission fluid level:
* Insufficient fluid level reduces the pressure in the system, which causes slipping and kicking.

3. Transmission fluid contamination:
* Dirty fluid can clog the channels and cause insufficient pressure, resulting in kicking.

4. Wear of friction clutches:
* Worn clutches can slip, resulting in kicking when shifting gears.

5. Torque converter malfunction:
* Torque converter problems can cause vibration and kicking when shifting gears.

6. Malfunction of the automatic transmission control unit (TCU):
* TCU controls the operation of the automatic transmission. Its malfunction can lead to incorrect shifting and kicking.

7. Oil filter clogged:
* A clogged oil filter restricts fluid flow, which can lead to insufficient pressure and kicking.

8. Deformation of the automatic transmission shaft:
*A deformed shaft can cause internal components to become misaligned and malfunction, resulting in kicking.

9. Engine problems:
* Engine problems such as rough idling can also affect the operation of the automatic transmission and cause kicking.

10. Incorrect automatic transmission programming:
* Automatic transmissions may require programming to adapt to a specific vehicle. Incorrect programming can lead to kicks and other problems.
