Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid pump.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the Vehicle: Use a jack and jack stands to safely elevate the vehicle.
2. Locate the Transmission Pan: Remove the undercarriage protection (if equipped).
3. Check Fluid Level and Condition: Remove the fill plug and check the fluid level. If low, proceed to drain and replace.
4. Drain Old Fluid: Using a socket set, remove the transmission pan bolts and drain the fluid into a suitable container.
5. Replace Filter (if applicable): Remove the old filter and install a new one.
6. Reassemble and Refill: Reinstall the transmission pan with a new gasket, torque the bolts to the manufacturer's specifications, and refill with the correct type of transmission fluid as specified in the owner's manual.

3. Inspect Gear Selector Linkage

Sub-steps:
1. Access Gear Selector Mechanism: Remove the center console trim to access the gear selector.
2. Check for Damage or Misalignment: Inspect the linkage for any signs of wear or misalignment.
3. Adjust or Replace as Necessary: Realign or replace any damaged components to ensure proper operation.

4. Check Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM: Typically found near the transmission or under the dashboard.
2. Inspect Connections: Ensure all electrical connectors are secure and free of corrosion.
3. Test Functionality: Use a multimeter to check for proper voltage and signals. If faulty, replace the TCM.
