- Low transmission fluid level
- Dirty or contaminated transmission fluid
- Faulty shift solenoid
- Faulty transmission control module (TCM)
- Mechanical issues within the transmission (such as worn gears or damaged synchronizers)
Recommended Steps:
1. Check the transmission fluid level and condition. If the fluid level is low, add the recommended type of fluid to the correct level. If the fluid is dirty or contaminated, it should be drained and replaced with new fluid.
2. Check for any diagnostic trouble codes (DTCs) stored in the TCM. These codes can provide more information about the source of the problem.
3. Check the shift solenoid and TCM for proper operation. If either of these components is faulty, it should be replaced.
4. If no DTCs are present and the shift solenoid and TCM are operating properly, the transmission may need to be overhauled or replaced.
Note: It is recommended to have a qualified mechanic diagnose and repair any transmission problems, as they can be complex and require specialized knowledge and tools.
