  4. Clean the transmission pan and replace the gasket.
  5. Reinstall the pan and torque bolts to manufacturer specifications (typically 10-12 ft-lbs).
  6. Refill the transmission with new Toyota ATF through the dipstick tube.

4. Inspect and Repair Wiring

• Inspect the wiring harness for any damaged insulation or frayed wires.
• Repair or replace any damaged connectors and ensure all connections are secure.
