i have a 1996 dodge 1500 4x4.just put new 5.9 motor in it.drove good for 3 months,driving home yesterday,stopped at stop sign would not move when i pressed the accelerater,there was no bang ding or any noise,no slippage,could this be a sensor or torgue converter.it cranks fine,even acts like it wants to move.any feedback would be gratefull,thank you
