Solution

1. Preparation

Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and check the fluid level; add the appropriate type of transmission fluid if low.
If the fluid is dark or has a burnt smell, proceed to replace the fluid and filter.

3. Replace Transmission Fluid and Filter

Drain the old transmission fluid using a fluid extractor or by removing the drain plug.
Remove the transmission pan to access the filter.
Replace the old filter with a new one, ensuring any seals are properly seated.
Reattach the transmission pan with a new gasket; torque the bolts to the manufacturer’s specifications (usually around 8-10 Nm).

4. Inspect and Repair Electrical Connections

Inspect the wiring harness and connectors for the TCM; repair any damaged wires.
Clean the connectors with electrical contact cleaner and ensure a secure fit.

5. Reconnect Battery and Test

Reconnect the battery and clear any stored error codes.
Start the engine and allow it to reach operating temperature, then test the shifting performance.
