Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is on a level surface and securely lifted with jack stands if needed.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if equipped) or access the fill plug.
Remove the dipstick or fill plug and check the fluid level; add the manufacturer-recommended transmission fluid if low.
If the fluid is burnt or contaminated, drain the old fluid using a fluid pump and replace it with new fluid.
Replace the dipstick or fill plug securely.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage under the vehicle.
Visually inspect the linkage for any signs of wear or damage.
If misaligned, adjust the linkage according to the manufacturer’s specifications to ensure proper engagement.

4. Test and Replace Brake Pedal Switch

Locate the brake pedal switch mounted on the brake pedal assembly.
Disconnect the electrical connector and use a multimeter to test for continuity when the pedal is pressed.
If faulty, replace with a new brake pedal switch and reconnect the electrical connector.

5. Check and Replace Transmission Control Module (if necessary)

Locate the transmission control module (usually near the transmission).
Inspect for any visible damage or corrosion on connectors.
If a fault is detected, replace the TCM with a new one and ensure it is programmed according to the vehicle specifications.
