Frequently Asked Questions
Will harsh shifting damage other components?
Yes, sustained harsh shifting can damage driveline components including axles, mounts, and U-joints.
Can a fluid flush help?
A fluid flush can sometimes clear debris from the valve body, but if the solenoid or valve is mechanically stuck, replacement is needed.
How do I know if it is the solenoid or valve body?
A technician can test solenoid resistance and operation. If the solenoid tests good, the valve body is the likely culprit.
