Ok. Picked up the new truck tonight and had a little trouble with the rpms. When I first ran it down the road I was goin 55 and the rpms were at about 2500-3000k. Got gas and I jumped on the highway and goin 60 it was close to 4500 about to be in the redline. Brought it back down to 50-55 and it was screaming at 4k. Anyone know what might be causing this? It's got the TH400 with no o/d, and in fact now that I think about it I don't think I even remember 3rd kickin in. The p/o said before I picked it up that he was replacin the gasket and somethin else on the tranny, sorry forget what.
