Had a temporary trans swap done on my 01 gtp with a trans from a 00 gtp,found the trans on c-list in steeger ill for 250......guy said the trans was fine and that he drove it and had no issues with it shifting or engaging,added a transgo shift kit and a new torque converter just to be precautious on codes and such until I can get my original one rebuilt by Andrew.trans is in now and it goes into reverse but here comes the kicker won't go into drive ,3,2, or 1 and when in drive as long as you are on flat surface and you rev the hejj out of it, it will do a slow roll almost as to say I wanna go but I'm gonna go at my own pace.
Any thoughts or info would be greatly appreciated,hopefully it is something minor (HOPEFULLY).
