scan for codes and see if trans is shifting into reverse it may be a cable problem.

Thanks brother, and yes thats what it is. I had it scanned for codes this morning. It looks like a easy job from the look of a few videos on youtube. Rather expensive at some of thr shop i called and being that i have two big boys in college playing football,and a daughter in her senior year and she running track in California next year, a junior and he do the most. Sports,band,choir and work sorry bro. So it pretty much is going like the cables on the carbonrater right?
