Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shocks.
Gather necessary tools and parts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and pull it out to check the fluid level.
If the fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.

3. Inspect and Repair TCM

Locate the transmission control module (usually found near the transmission).
Disconnect the wiring harness from the TCM.
- Tools Required: Socket set, screwdriver
Inspect for corrosion or damage on the connectors.
If damaged, replace the TCM with a new unit, using the specific part number for your model.

4. Examine Gear Shift Linkage

Locate the gear shift linkage under the vehicle.
Check for any obstructions or damage.
If the linkage is damaged, replace it with a new one.
- Tools Required: Wrench set, screwdriver

5. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes that may have been set.
This resets the transmission control system.
