After changing the oil in the automatic transmission, kicks are possible due to the following reasons:
1. Incorrect oil level:
*If the oil level is too low, the oil pump cannot generate enough pressure to operate the transmission properly.
*If the oil level is too high, it may foam and cause slipping.
2. Incompatible ATF:
*Only use ATF fluid recommended by the manufacturer for your transmission model. Incompatible fluid may cause friction or foaming problems.
3. Dirty filters:
*If the oil filter or valve body filter is clogged, it can restrict oil flow and cause kicking.
4. Faulty solenoids:
* Solenoids are responsible for shifting gears in an automatic transmission. A faulty solenoid can cause shifting problems, resulting in kicking.
5. Wear of internal components:
* Worn clutches, gaskets or bearings can cause slipping and kicking.
6. Air in the system:
* If there is air in the system, it may cause insufficient oil pressure and kicking.
7. Electronic control problems:
* Sensors or electronic components that control the automatic transmission may fail, resulting in incorrect operation of the transmission.
8. Mistakes when changing the oil:
* Improperly draining old oil or not filling enough with new oil can cause problems.
What to do:
*Check the oil level and make sure it is as recommended.
*Make sure the correct ATF is used.
* Replace the oil filter and valve body filter (if required).
* Scan the transmission for trouble codes.
* Visit an auto mechanic for further diagnosis and repairs.
