I replaced the engine in my 03 explorer and now it won't shift into gear?
Hello, Several things to check: Did converter get jammed into tranny and break pump gears...? Are you 4WD, and is the transfer case in gear or neutral...? The electrical bulkhead going into the tranny top and the selector switch bulkhead going into the side over the selector valve are REALLY important.... A gauge connected to the line pressure port is the quickest way to tell if the tranny is working. Hope this Helps, AskTrannyMan
