• Tools Required: Socket set, torque wrench, replacement solenoids.
• Remove the transmission pan by unbolting it and draining any remaining fluid.
• Access the solenoids and remove the faulty ones by unbolting them.
• Install new solenoids and torque to the manufacturer's specifications.
• Reinstall the transmission pan with a new gasket and torque to specifications.

5. Final Checks
