Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or access point.
2. Remove the dipstick and wipe it clean with a lint-free cloth.
3. Reinsert the dipstick and remove it again to check fluid level; it should be within the marked range.
4. If low, add the correct type of transmission fluid as specified in the owner’s manual.
5. If fluid is dark or has a burnt smell, proceed to drain and replace the fluid.

3. Inspect and Test Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch, usually mounted on the brake pedal assembly.
2. Disconnect the wiring harness from the brake switch.
3. Using a multimeter, test for continuity; it should show continuity when the pedal is depressed.
4. If faulty, replace the brake pedal switch.

4. Examine Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM, typically found near the transmission or under the dashboard.
2. Inspect the connectors for any signs of corrosion, damage, or looseness.
3. If necessary, clean the connectors with electrical contact cleaner.
4. Reconnect the TCM and ensure a secure fit.

5. Verify Gear Shift Mechanism

Sub-steps:
1. Inspect the gear shift lever for any obstructions or misalignment.
2. Ensure that the linkage connecting the shifter to the transmission is intact and functioning.
3. If misaligned, adjust the linkage according to the service manual specifications.
