Was going down the road an hear a little noise an hit the gas an all it would do is Rev up. Had towed home, the shifter works fine when I put it in any of the gears it want move. It makes a little noise under where thettransmission is but it only makes it some times when I start it up. Never had any problems with it before this was all of a sudden. Anyone can help me out with what it could be. Thanks
