OK all. I am having a new problem now. On ocassion my truck will die un reverse. I don't have any problems in drive and it only seems to occure when I am moving very slowly. Such as backing up a trailer or going up a curb on incline. Not sure what may be causing this. Does anyone have any ideas? Any help would be very appreciated as I don't know where to begin looking for it. Thanks in advance. I have also started to notice that occasionally there is a sqealing noise coming from somewhere when in reverse. Not sure if it may be tranny but only makes it in reverse and not all the time.
