1. Remove the transmission fluid dipstick and wipe it clean.
2. Insert a funnel and pump new transmission fluid (check owner's manual for the correct type) into the transmission until the fluid level is correct.
3. Start the engine, cycle through the gears, and recheck the fluid level, adding fluid as necessary.

3. Inspect and Adjust Transmission Linkage

Tools Required: Socket set, wrenches, pliers.
Sub-steps:
1. Locate the transmission linkage under the vehicle.
2. Check for loose bolts and tighten them to the manufacturer’s specified torque.
3. If the linkage is damaged, replace it with a new part.

4. Replace the Brake Switch

Tools Required: Screwdriver, replacement brake switch.
