Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Fluid Check:
- Remove the transmission dipstick and wipe it clean.
- Insert it back and remove it again to check the fluid level and condition.
Fluid Replacement (if necessary):
- Place a drain pan under the transmission pan and remove the pan bolts.
- Allow the old fluid to drain completely.
- Replace the filter if applicable, and install a new gasket.
- Reassemble the pan and torque the bolts to the manufacturer's specifications.
- Fill the transmission with the recommended fluid type through the dipstick tube.

3. Inspect and Repair Shifter Mechanism

Remove the center console trim to access the shifter assembly.
Inspect for any broken components or foreign objects obstructing the shifter.
Replace any damaged parts and reassemble the console.

4. Check Electrical Connections

Inspect the TCM wiring harness for any loose or damaged connections.
Use a multimeter to test the continuity of the TCM and associated sensors.
Repair or replace faulty wiring as needed.
