I have been having some problems with my 48re when im cruising along at like 50 and I floor it when it downshifts it wont shift back up it just sits there and slips its an all billet tranny with about 25k miles on it do you guys have any idea what it could be? it should still be under warranty but I am just trying to get a feel for some possibilities, just in case they try to feed me some BS when I take it in
