Truck: 98 GMC K1500
So about a month ago my transmission wouldn't go into overdrive or something like and so we rebuilt it. The problem now is after we put it back in it doesn't seem to shift at all and also the manual gear don't even work either. My uncle thinks that it wont shift out third gear I don't know if that makes sense but all I know is it doesn't shift at all but the reverse works just fine and whenever you hit 30 mph the rpms go up high and by the time you hit 55 mph the rpms are at 3500.
Any help with this would really be appreciated.
