Possible reasons:
1. Incorrect solenoids:
* Incorrect or faulty solenoids supplied.
* Solenoids are incorrectly installed or loose.
2. Wiring problem:
* Damaged or incorrectly connected wiring between the solenoids and the Transmission Control Module (TCM).
3. Faulty TCM:
* The TCM that controls the solenoids may be faulty.
4. Incorrect adaptation:
*After replacing solenoids, transmission adaptation is required to allow the TCM to learn their characteristics.
5. Other mechanical problems:
* Wear on internal transmission components such as friction plates or bearings can cause kicking.
Troubleshooting:
1. Checking solenoids:
* Make sure the correct solenoids are installed.
* Check that they are installed correctly and are not damaged.
2. Wiring check:
* Check wiring for damage or loose connections.
* Make sure all wires are properly connected to the solenoids and TCM.
3. TCM check:
* Diagnose the TCM using a trouble code scanner.
*Try reprogramming the TCM or replacing it if necessary.
4.Transmission adaptation:
* Perform the transmission adaptation procedure according to the manufacturer’s instructions.
5. Finding mechanical problems:
*If other steps fail, you may need to run a comprehensive transmission diagnostic to identify any mechanical problems.
Adviсe:
*Consult a qualified mechanic for automatic transmission diagnosis and repair.
* Use only original or high quality spare parts.
*Follow manufacturer’s instructions for replacing solenoids and adapting transmission.
* Perform automatic transmission maintenance regularly to avoid serious problems.
