Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Brake Pedal Switch

Locate the brake pedal switch mounted on the brake pedal assembly.
Disconnect the electrical connector from the switch.
Remove the switch by unscrewing it from the mounting bracket.
Install the new brake pedal switch and reconnect the electrical connector.
Reconnect the negative battery terminal.

3. Check and Refill Transmission Fluid

Locate the transmission dipstick (if equipped) or fill plug.
Remove the dipstick and check the fluid level; it should be within the recommended range.
If the fluid is low, use an appropriate funnel to add the correct type of transmission fluid (check owner’s manual for specifications).
Replace the dipstick or fill plug securely.

4. Test Gear Shift Interlock System

Access the gear shift assembly by removing the trim surrounding the gear shift lever.
Inspect the interlock mechanism for any obstructions or damage.
Ensure the mechanism moves freely and engages properly.
Reassemble the trim once checked.

5. Clear Any Diagnostic Codes

Using an OBD-II scanner, clear any trouble codes related to the transmission.
Monitor the system for any immediate reoccurrence of codes after the vehicle is started.
