Still has reverse, and when you apply trans brake in first, it tries to back up. 727 trans was rebuild be decent shop around 25 passes. Not sure who valve body, but don't need to apply trans brake to back up in reverse. What first thing I should check in the morning? Dragweek coming fast.

The Belleville spring on the left is more robust than the one on the right but requires the matching piston. The INTERNET, the MISinformation superhighway
