Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to avoid electrical issues.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check fluid level.
If low, add the manufacturer-recommended transmission fluid type (check the owner’s manual for specifications).

3. Inspect Gear Shift Linkage

Locate the gear shift linkage connected to the transmission.
Visually inspect for any damage or disconnections.
Reconnect or replace any damaged components as necessary.

4. Test Brake Pedal Switch

Locate the brake pedal switch and check for proper operation.
Use a multimeter to test for continuity when the pedal is depressed.
Replace the switch if it does not function correctly.

5. Check Transmission Control Module (TCM)

Disconnect the TCM connector and inspect for corrosion or dirt.
Clean the connector with electrical contact cleaner.
Reconnect the TCM and ensure it is securely mounted.
