Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid any electrical issues.

2. Transmission Fluid Check

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until the correct level is reached.

3. Inspect and Adjust Linkage

Locate the gear shift linkage and cables.
Check for any signs of wear or damage; if found, replace the affected components.
If misalignment is present, adjust the linkage according to the specifications provided in the vehicle's service manual.

4. Test Transmission Control Module (TCM)

Reconnect the battery.
Using a multimeter, test the power and ground circuits to the TCM.
If the TCM is faulty, replace it according to manufacturer specifications, ensuring proper calibration after installation.

5. Reassemble and Test Drive

Reassemble any components removed during inspection and repair.
Ensure all connections are secure and fluid levels are correct.
Test drive the vehicle to confirm the issue is resolved.
