Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel
Remove the transmission fluid dipstick and check the fluid level. If low, top off with the manufacturer-recommended fluid type.
Inspect the fluid for burnt odor or metallic particles; if present, a transmission service may be required.

3. Inspect Wiring and Connectors

Tools Required: Multimeter, socket set
Visually inspect the wiring harness and connectors to the TCM for any signs of damage or corrosion.
Use a multimeter to check for continuity and proper voltage at the TCM connections.

4. Test the TCM

Tools Required: Multimeter
Follow the vehicle’s service manual to perform a diagnostic test on the TCM.
Check for proper input/output signals according to specifications. Replace if faulty.

5. Repair or Replace Affected Components

If any faulty sensors or wiring are found during inspection, replace them according to manufacturer specifications.
Use a torque wrench to ensure any bolts or connectors are tightened to the recommended torque values.
