Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before checking the transmission fluid.

2. Transmission Fluid Change

Place a fluid catch pan under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan to drain old fluid.
Inspect the transmission filter and replace if necessary.
Clean the pan with a non-abrasive cleaner and replace the pan gasket.
Reinstall the transmission pan and torque the bolts to the manufacturer's specifications.

3. Reset Transmission Control Module (TCM)

Reconnect the battery and start the engine.
Use the OBD-II scanner to clear any existing transmission-related error codes.
Perform a TCM reset by following the manufacturer's specified procedure (refer to the service manual for exact steps).

4. Inspect and Adjust Shift Linkage

Locate the shift linkage and inspect for any wear or misalignment.
If any issues are found, adjust the linkage according to specifications or replace it if necessary.
