OK today we are tuning my truck. We are getting on it and what not. well about the 3rd full pull I let out at the end and try to slowly get back into it. rpms go and truck pulls EVER so slightly but not much. I have a very slight VERY slight pull in 3rd and OD. But not much. Is that the 3-4 clutch pac? anythign else it coudl be. after driving about another mile like this and pulling off the interstate and letting the truck sit maybe 2 minutes the tranny temp was 189. I have a pretty large cooler also. THis is a supposedly built tranny with the Z-pack clutches I think?
