Reasons and solutions for automatic transmission kicking when shifting down
1. Low transmission fluid (ATF) level
* Check the ATF level and add to the correct level.
* Leaks in the transmission system can lead to low fluid levels and shifting problems.
2. Contaminated ATF
*Old or contaminated ATF can cause shifting problems and jerking.
* Timely ATF replacement according to manufacturer’s recommendations will prevent contamination and shifting problems.
3. Faulty solenoids
* Solenoids control the flow of ATF in the transmission.
* Faulty solenoids can cause rough shifting, slipping and kicking.
* Diagnosing and replacing faulty solenoids may solve the problem.
4. Wear of friction discs
* Friction discs transfer power from the engine to the transmission.
* Over time, friction discs wear out, resulting in slipping, difficult shifting and kicking.
*Replacement of worn friction plates will restore smooth shifting.
5. Faulty Transmission Control Module (TCM)
* The TCM controls the operation of the transmission.
* A faulty TCM may send incorrect signals, resulting in hard shifting and kicking.
* Diagnosis and reprogramming or replacing the faulty TCM may resolve the problem.
6. Mechanical problems
*In rare cases, mechanical problems such as faulty gears or bearings can cause kicking when shifting down.
* Repair or replacement of damaged components is necessary to correct the problem.
7. Incorrect settings or adjustments
* Improper adjustment of the shift cable or other transmission system components may result in hard shifting.
*Adjust or replace incorrectly adjusted components to ensure smooth shifting.
8. Software problems
*In some car models, software errors may cause gear shifting problems, including kicking.
*Updating the transmission software may resolve the issue.
