Did he replace the hidden O rings at the base of the clutch baskets? If you don't do that, the leakage will not allow the clutches to fully engage. To replace the O rings you have to drill out several rivets to get to the O ring. You then have to tap the rivet holes and put in a flat head screw. Ask him if he did that.
