Tools Required: Wrench set, screwdriver.
Locate the transmission linkage and inspect it for any signs of wear or misalignment.
If adjustments are needed, loosen the linkage bolts and reposition the linkage according to the manufacturer's specifications.
Tighten the bolts securely after adjustment.

4. Replace Brake Switch (if faulty)

Tools Required: Screwdriver, replacement brake switch.
Locate the brake switch, usually found near the brake pedal.
Disconnect the wiring harness from the faulty switch.
Remove the old switch and install the new one, ensuring it is properly aligned.
Reconnect the wiring harness.

5. Inspect Transmission Mount

Tools Required: Jack, jack stands, socket set.
Use a jack to support the transmission.
Inspect the transmission mount for cracks or excessive wear.
