Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid, funnel, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery to avoid any electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick or fill plug and check fluid level.
3. If fluid is low, add the recommended transmission fluid (refer to owner’s manual for specifications).
4. If the fluid is dirty or burnt, proceed to drain and replace the fluid.
5. To drain, remove the transmission pan bolts using a socket set. Carefully lower the pan and drain the fluid into a catch basin.
6. Clean the transmission pan and replace the filter if applicable.
7. Reinstall the pan with new gasket and torque bolts to manufacturer specifications.
8. Refill the transmission with new fluid using a funnel.

3. Inspect and Repair Shift Linkage

Sub-steps:
1. Locate the shift linkage mechanism under the vehicle.
2. Check for any visible damage or misalignment in the linkage.
3. Tighten any loose connections or replace damaged components as necessary.
4. Ensure proper adjustment so the linkage correctly engages the transmission.

4. Test Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch, usually mounted on the brake pedal assembly.
2. Inspect for correct operation; ensure it is making contact when the brake is applied.
3. Replace the switch if it does not function properly.
