- No leaks
- Minimal noise
- Easy to turn if off the ground
- Easier to turn if revved to 2000 RPM, but still difficult
Possible Diagnosis
Stuck Valve?
Possible Fix?
As an alternative to replacing the entire system, this video by Scotty Kilmer suggests using a product called Trans Tune to attempt to clean the internals of the system. I don't know enough about this to know if this is a good idea, or if there are potential bad side effects (I don't want to destroy seals and the like, etc.)
