Solution

1. Preparation

Gather the necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: OBD-II scanner, jack and jack stands, transmission fluid gauge, socket set, torque wrench, multimeter.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission fluid dipstick or fill plug.
3. Remove the dipstick or fill plug and check the fluid level. If low, add the manufacturer-recommended transmission fluid.
4. If the fluid is dirty or burnt, drain the old fluid by removing the drain plug and replace it with new fluid.
5. Reinstall the drain plug and refill the transmission with the correct amount of new fluid through the dipstick or fill hole.

3. Inspect and Repair Transmission Linkage

Sub-steps:
1. Visually inspect the transmission linkage for any signs of wear, damage, or disconnection.
2. If misalignment is detected, adjust the linkage according to the manufacturer specifications.
3. Replace any damaged components if necessary.

4. Test and Replace Brake Light Switch (if faulty)

Sub-steps:
1. Locate the brake light switch under the dashboard near the brake pedal.
2. Disconnect the wiring harness and use a multimeter to test for continuity when the brake is pressed.
3. If defective, replace the brake light switch with a new one and reconnect the wiring.

5. Recheck and Clear Codes

Sub-steps:
1. Reconnect the OBD-II scanner and check for any remaining trouble codes.
2. Clear any codes that were previously stored.
3. Start the vehicle and attempt to shift into gear again.
