I have a 95 Pathfinder SE With an Auto Trans that will not go in reverse. when I put the shifter in R the tach goes lower like the Trans is engaged but then it wont move. I rev the motor a little to see if it will grab, and still nothing. All the other P and D gears work fine. The Chiltons manual is worthless on this. Is there some kind of electronic control or vacuum thing that may be causing this ? Has anyone else had this trouble? Don't want to shell out 2K for a new tranny if I don't have to. Any help would be greatly appreciated Thanks in advance....Rip

Chances are you have an internal transmission problem. Pull the transmission pan and inspect for clutch material and metal shavings. If you have any questions, feel free to e-mail me at Ray Brandt Answer Guys (answerguys@raybrandtnissan.net)
