Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock or short circuits.

2. Inspect Transmission Fluid

Remove the transmission dipstick (if equipped).
Wipe the dipstick clean and insert it back into the tube, then remove it again to check fluid level.
If fluid is low, add the manufacturer-recommended transmission fluid.
If fluid is discolored or smells burnt, proceed to replace the fluid and filter.

3. Check Wiring and Connectors

Locate the TCM and inspect the wiring harness and connectors for any signs of wear, fraying, or corrosion.
Clean any corroded connections with an electrical contact cleaner.
Repair or replace damaged wiring or connectors as necessary.

4. Test TCM Functionality

Using a multimeter, check the TCM power and ground connections according to the vehicle's wiring diagram (refer to the service manual).
If the TCM is not receiving proper voltage, trace the wiring back to the source.
If the TCM is malfunctioning, it may need to be replaced.

5. Reassemble and Test

Reconnect the battery and ensure all connectors are secure.
Clear any existing DTCs using the OBD-II scanner.
Perform a test drive to confirm the issue is resolved.
