Solution

1. Preparation

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

2. Check Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick or fill plug and check the fluid level; add fluid if low.
Inspect the fluid for discoloration or burnt smell; replace if necessary.

3. Inspect Transmission Control Module (TCM)

Remove the TCM from its mounted position.
Inspect the wiring harness for corrosion or loose connections.
Clean the connectors with electrical cleaner and allow them to dry.

4. Replace Faulty Sensors

If the throttle position sensor or vehicle speed sensor is faulty, remove the old sensor using a socket set.
Install the new sensor by aligning it properly and securing it with the specified torque (refer to the repair manual for exact values).
Reconnect the electrical connectors.

5. Reassemble and Reconnect Battery

Reattach the TCM and secure it in place.
Reconnect the battery terminals ensuring a tight connection.
