Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Transmission Fluid Check

Locate the transmission dipstick (if equipped).
Remove the dipstick, wipe it clean, and reinsert it to check fluid level.
If low, add the manufacturer-recommended transmission fluid to the proper level.

3. Inspect Wiring and Connectors

Remove the protective cover over the TCM and inspect the wiring harness.
Look for frayed wires, loose connections, or corrosion.
Repair or replace damaged wires/connectors as necessary.

4. Test Transmission Control Module (TCM)

Disconnect the TCM from the wiring harness.
Use a multimeter to check the power and ground circuits according to the vehicle's service manual specifications.
If the TCM is faulty, replace it with a new unit.

5. Replace Speed Sensors (if necessary)

Identify and remove the input and output speed sensors from the transmission.
Install new sensors, ensuring they are securely fitted and properly connected.
Torque the sensors to the manufacturer's specifications.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored codes.
Start the engine and check for the check engine light.
