Reasons why the automatic transmission kicks when switching from 1 to 2:
1. Transmission fluid level is low:
*Lack of fluid results in insufficient pressure, making gear shifting difficult.
*Check the transmission fluid level and add it to the proper level.
2. Contaminated or burnt transmission fluid:
* Contaminated fluid may contain particles or deposits that will prevent smooth shifting.
* Replace transmission fluid according to your maintenance schedule.
3. Faulty shift solenoid:
* Solenoids control transmission fluid flow and shift gears.
*A faulty solenoid can cause delayed or harsh shifting.
* Check and replace faulty solenoids.
4. Defective valve body:
* The valve body controls the flow of transmission fluid.
*A worn or faulty valve body can interfere with smooth shifting.
* Check and replace faulty valve body.
5. Wear of friction linings:
* The friction linings in the gearbox wear out over time.
*Excessive wear may cause slippage or harsh shifting.
* Replace worn friction linings.
6. Faulty torque converter:
* Torque converter ensures smooth power transfer from engine to gearbox.
*A faulty torque converter may cause vibration or harsh shifting.
* Check and replace the faulty torque converter.
7. Malfunction in the electronic transmission control module (TCM):
* The TCM controls the operation of the transmission.
* A malfunctioning TCM may affect smooth shifting.
* Scan the TCM for trouble codes and replace it if it is faulty.
8. Incorrect adjustment of the gear shift cable:
* Cable-controlled transmissions may have an incorrectly adjusted cable, resulting in harsh gear shifts.
*Adjust the shift cable to specifications.
