Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands if needed.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Check and Replacement

Check Fluid Level
- Remove the transmission dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the fluid level. It should be within the "full" range.
Change Fluid if Contaminated
- Place a drain pan under the transmission and remove the drain plug.
- Allow old fluid to completely drain.
- Replace the drain plug and torque it to the manufacturer’s specifications (typically around 20-30 ft-lbs).
- Refill with new transmission fluid (refer to the owner’s manual for specific type and quantity).

3. Inspect and Adjust Gear Shift Linkage

Locate the gear shift linkage under the vehicle.
Inspect for wear or damage; replace any damaged components.
Adjust the linkage as needed to ensure proper alignment and operation.

4. Replace Brake Switch (if faulty)

Locate the brake switch near the brake pedal.
Disconnect the electrical connector and remove the switch.
Install the new brake switch and reconnect the electrical connector.

5. Check Transmission Control Module (TCM)

Inspect the TCM for any visible damage or loose connections.
If necessary, replace the TCM according to manufacturer instructions.
