Possible reasons why the automatic transmission kicks after an oil change:
* Incorrect oil: Make sure you are using the manufacturer’s recommended oil for your vehicle. The wrong oil can cause gear shifting problems.
* Not enough fluid: check the automatic transmission fluid level using the dipstick or through a special inspection hole. If the fluid level is too low, it can cause problems with shifting.
* Dirty filter: when changing the automatic transmission oil, you should also replace the filter. If the filter is clogged, it can restrict fluid flow and cause jerking.
* Defective solenoid: The shift control solenoid is an electronic device that controls fluid flow. A faulty solenoid can lead to problematic shifting.
* Wear of internal components: If the automatic transmission has already begun to wear out, changing the oil can only slightly improve the situation. Repair or replacement may be necessary to correct the root cause.
* Electrical problems: Electrical problems, such as faulty sensors or wiring, can interfere with the operation of the automatic transmission.
* Blockage in the radiator: the automatic transmission radiator cools the fluid. A clogged radiator can cause the fluid to overheat and cause problems with shifting.
Actions to take:
*Check oil level: Make sure the fluid level is at the correct level.
* Check the condition of the filter: replace the filter if it was not replaced during service.
* Scan for Trouble Codes: Scan the ECU for trouble codes that may indicate specific problems.
*Contact a service center: If you cannot solve the problem yourself, please contact a qualified service center for diagnosis and repair.
