I am not sure where the rpm was, but I know it was above 2800, because I remember seeing it at about 2800 or so when I was going around 90-95 maybe.hd
mine did the same 3-4 times as ecc said and were the rpms high at 100mph
i lost reverse 3-4 times
the codes i set where incorect 5th gear ratio anything with TCM basicly
i think we need to start a "get hdmax his trans" fund
I am all for a fund raising party for me
