Re: Speed sensor internal transmission failure-
Welcome to the garage. Which engine/transmission does the jeep have? Do you know the actual fault code?
Since you say its internal, it probably has the 3.7 engine with the NAG 1 transmission. No experience on that transmission, but i heard that the speedsensor is part of an assy, which will be changed as one. I expect some other member with experience on this will chime in. Are you going to do the job yourself?
