I've got a 7140 magnum that I rebuilt all the internal clutch packs because all the friction material was gone. The unit has 8000 hours on it. I got the unit back together and now I've got no reverse? It shifts through all the forward gears well. The FNR cable is not broke and I have adjusted it about 100 times. I have done the adjustment procedure through the book and still have no reverse? I have taken the valve back off and took the valve apart hoping to find some debris or something in the valve. I am still experiencing the no reverse and when I put it in reverse it almost wants to creep forward. It will move forward just a fuzz and then stop. Could I have missed something? Thanks a ton.
