whew, glad to see that somebody has the same problem(i guess). i turned off the trac.and vsc and it was in drive.would not shift out of 4th. turned everything back on and it shifted fine. tried it again with everything off and it did fine. i thought maybe the trans wasnt fully warmed up or something,dunno. was kinda getting nervous about it.
With all the trac. stuff off it still feels like its not getting all the power that you would expect out of that hoss engine.
