Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, fluid catch pan, socket set
Locate the transmission fluid dipstick (if applicable) and remove it.
Check fluid level and condition; if low or contaminated, drain the old fluid using the drain plug.
Replace with manufacturer-recommended transmission fluid; refill to the appropriate level using the funnel.

3. Inspect and Repair Gear Shifter Linkage

Tools Required: Socket set, screwdriver set
Remove any trim panels around the gear shifter to access the linkage.
Inspect the linkage for any signs of wear or damage; replace any broken components.
Reassemble the gear shifter assembly and trim panels.

4. Test and Replace Brake Pedal Switch

Tools Required: Multimeter, socket set
Locate the brake pedal switch and use the multimeter to test for continuity.
If faulty, disconnect the wiring harness and remove the switch.
Install a new brake pedal switch and reconnect the wiring harness.

5. Transmission Control Module (TCM) Reset

Tools Required: OBD-II scanner
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes and reset the TCM.
Perform a test drive to ensure normal operation.
