speedo jumping and sometimes quits?

Anyone have any experance with this? Think this would be a speed sensor? If so can I just buy a new one and put it in or would I need to know what trans I have. Also how do I identify what trans I have? Thanks guys.

I would highly recommend you pick up a Haynes or Chilton's repair manual from the local auto parts store.

You'll be able to see and read exactly how to replace or repair your speed sensor.

I would bet its the speed sensor. A Chilton or Haynes manual should show the exact location of the speed sensor, it's easy to change, it bolts right into the tranny. Just watch out for any fluid that may leak out. Best to do it when the car is cold.

You can always get a build sheet for your Jeep, it will tell you what tranny you've got.

I had the speed sensor go in my '93 a long time back, right before I sold it. It did the same exact thing you're describing. It's a fairly common problem with GC's, if I'm not mistaken.

My wife's Caravan had the speed sensor go bad, it was acting like that then it went into "limp" mode. That was a pain!
