Lance my guess is the problem is the common one with the rear servo. It has an internal cushion spring that compresses as the outer spring is extending making the servo slow to release. It's there to ease the release of the rear band but it's really a hinderance. It doesn't show up when the trans. is driven in drive cause the rear band servo isn't applied. The Trans-go shift improver kits (and some others) have a spacer that you install in the rear servo to eliminate the action of the one spring working against the other and it generally eliminates the overlap problem. Do you still have the Trans-go info I sent you? That was you I sent it to a few months back, wasn't it? If so it shows installing the spacer. I have always used the Trans-go kits spacers but I imagine you could make one pretty easy if this is your only complaint. ACE hardware sells a lot of different spacers too. They might have something you could cut down and make work. Whatever you do make sure and get it remedied quick cause overlap is a trans. killer and yours sounds bad.
