Repair Instructions

Step 1: Transmission Fluid Service

Check Fluid Level: If the fluid is low, fill it to the recommended level using Toyota WS transmission fluid.
Fluid Change: If the fluid is dark or burnt:
- Raise the vehicle securely on jack stands.
- Remove the transmission fluid pan and filter.
- Replace the filter and clean the pan.
- Reinstall the pan with a new gasket and refill the transmission with fresh fluid.

Step 2: Addressing Fault Codes

Code Specific Repairs:
- For codes indicating sensor issues (e.g., TPS, VSS), replace the faulty sensors.
- For solenoid-related codes, replace the shift solenoids as required.

Step 3: Electrical Repairs

Repair/Replace Damaged Wiring:
- If any wiring or connectors are damaged, repair or replace them as needed.
- Ensure all connections are secure and free from corrosion.

Step 4: TCM Reprogramming/Replacement

If the TCM is malfunctioning:
- Reprogram: Some issues may be resolved by reprogramming the TCM using a scan tool that supports programming.
- Replace: If reprogramming does not resolve issues, consider replacing the TCM.

Step 5: Test Drive

Final Checks: After repairs, take the vehicle for another test drive.
Monitor Performance: Ensure that the shifting has returned to normal and that no warning lights reappear.

Conclusion

If after completing the above steps the issue persists, it may be necessary to take the vehicle to a professional transmission specialist for further diagnosis, as internal transmission issues may require extensive repair or replacement.
