2. Inspect and Replace Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch, typically found at the top of the brake pedal assembly.
2. Disconnect the electrical connector from the brake pedal switch.
3. Test the switch with a multimeter to check for continuity when the pedal is pressed.
4. If defective, remove the old switch by unscrewing it from the bracket.
5. Install the new brake pedal switch and reconnect the electrical connector.

3. Check and Replace Fuses

Sub-steps:
1. Open the fuse box and locate the fuses related to the transmission (refer to owner’s manual).
2. Visually inspect the fuses for any signs of damage.
3. Replace any blown fuses with new ones of the same amperage.

4. Inspect Shift Cable and Linkage

Sub-steps:
1. Locate the shift cable and linkage assembly connecting the gear lever to the transmission.
2. Inspect the cable for any signs of fraying or disconnection.
3. If damaged, remove the retaining clips and disconnect the cable from both the gear lever and the transmission.
4. Install the new cable by reversing the disassembly process, ensuring proper alignment.

5. Check Transmission Control Module (TCM)

Sub-steps:
1. Scan the vehicle for any TCM-related DTCs.
2. If specific codes indicate TCM failure, remove the TCM from its mounting location.
3. Inspect the connectors for corrosion or damage.
4. Replace the TCM if necessary, following manufacturer guidelines for programming.
