Possible reasons why the automatic transmission kicks after a partial oil change:
1. Incorrect oil level
* Make sure that the oil level in the automatic transmission corresponds to that recommended by the manufacturer. Too high or low oil level can lead to problems with the automatic transmission.
2. Incompatible oil
* Use the type and brand of oil recommended by the automatic transmission manufacturer. Unsuitable oil can damage the automatic transmission and cause kicking.
3. Dirty automatic transmission filter
* If the automatic transmission filter was not replaced during a partial oil change, there may be contaminants in it that restrict oil flow and cause kicking.
4. Worn components
* In some cases, a partial oil change may reveal worn automatic transmission components that were causing shifting problems.
5. Solenoid failure
* Solenoids in the automatic transmission control oil flow and gear shifting. A failed solenoid can cause shifting problems and kicking.
6. Electronic problems
* Problems with automatic transmission electronic components, such as the control module (TCM), can also cause shifting noise.
7. Contaminated oil
* If there were already contaminants in the oil before the partial change, they could clog the channels and cause shifting problems.
Solution:
1. Check the oil level and make sure it is correct.
2. Compare the brand and type of oil to the manufacturer’s specifications.
3. Replace the automatic transmission filter if it is very dirty.
4. Have the transmission checked by a qualified mechanic and check for other possible causes.
5. Repair any problems found, such as faulty components or electronic problems.
6. If necessary, a complete automatic transmission oil change may be required to remove contaminants.
