I have a 1997 gt in oh which the engine jus got rebuilt. When I got the car back the shop installed MLPS wrong. Now that that is fixed here's the issue. 1) car won't shift 1-2 properly. In D it wants to over rev like crazy. Then when I let off the gas a little and drop the rpms it shifts. This doesn't happen when I manually shift 1-2. Beyond that all other gears work fine until...... 2) in 3-4 + OD when I gun it it seems to get no power and rev high then again when I let off it catches. Only in WOT though does it do this. So anyone have any idea? I jus got back home from Afghanistan to find the engine stuck (that's why it was replaced) and now I don't want to do the same to the trans.
