Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level; add fluid if low.
2. If the fluid is dark or burnt, drain the old fluid using a fluid pump or drain plug.
3. Replace the transmission filter if equipped; remove the transmission pan, replace the filter, and reinstall the pan with a new gasket.
4. Refill the transmission with the manufacturer-recommended fluid type to the correct level.
Tools Required:
- Fluid pump
- Socket set
- Torque wrench
- New transmission fluid
- New transmission filter and gasket (if applicable)

3. Inspect and Replace Components

Sub-steps:
1. Inspect the transmission mounts for any signs of wear or damage; replace if necessary.
2. If error codes indicate a faulty TCM, replace the module following the manufacturer’s instructions.
3. Check wiring and connectors for corrosion or damage and repair as necessary.
Tools Required:
- Socket set
- Multimeter
- Torque wrench

4. Test Drive

After repairs, reconnect the battery terminal.
Start the vehicle and perform a test drive to assess shifting performance.
Monitor for any slipping or abnormal sounds.
