Hey guys have finally got my new engine in and box, everything runs great! now problem?? my auto drives good shifts all gears and kicks back gears fine but when trying to drop back to low gear or down shift theres nothing? If take off in first will still shift all the way to 4th!
I've try another inhibitor switch,oil is all good, plugs all on tight and clean,tryed changing ecu! still can't get it to hold low gear?
this box worked great in other car and nothing changed execept engine?
Also box has 3000 hi-stall but again was working in other car.

Any help would be great thanks!!
