Remove the transmission pan by unscrewing the bolts, then carefully lower it to avoid spilling fluid.
Remove the old filter and install the new filter, ensuring it fits securely.
Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications.

5. Replace Brake Pedal Switch (if necessary)

Tools Required: Screwdriver set
Locate the brake pedal switch above the brake pedal.
Disconnect the wiring harness and remove the bolts securing the switch.
Install the new brake pedal switch and reconnect the wiring harness.
