Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Transmission Fluid

Tools: Transmission fluid pump, socket set, fluid catch pan.
Remove the transmission fluid drain plug and allow old fluid to fully drain into the catch pan.
Inspect the drained fluid for metal shavings or burnt smell, indicating potential internal damage.
Reinstall the drain plug and torque it to the manufacturer’s specifications.
Using a transmission fluid pump, refill the transmission with the manufacturer-recommended fluid type.
Start the engine and cycle through the gears to ensure proper fluid distribution.

3. Inspect Transmission Linkage

Tools: Wrench set, flashlight.
Visually inspect the transmission linkage connected to the transmission for any signs of wear or damage.
If necessary, adjust or replace the linkage to ensure it is properly aligned and functioning.

4. Test Brake Pedal Switch

Tools: Multimeter.
Locate the brake pedal switch and test for continuity using a multimeter while pressing the brake pedal.
If the switch is faulty, replace it with a new one and ensure it is properly adjusted.

5. Reprogram Transmission Control Module (if necessary)

Tools: OBD-II scanner with programming capability.
Connect the OBD-II scanner to the vehicle and perform any necessary software updates or reprogramming for the transmission control module.
Follow the on-screen instructions to complete the programming process.
