speedometer/idle issue
I have a 99 WJ. It's doing something weird that I can't put my finger on. When I first start down the road with my WJ the speedometer doesn't work. Then it starts jumping around and at the same time it starts shifting back and forth between gears. Then after a little bit the speedometer starts working fine and the shifting issue stops. Then after driving for a while the speedometer will either go back to zero or start bouncing all over the place and the shifting issue starts back up again. I'm lost. Any help would be great. Thanks.

Thru AutoZone there is a Transmission Speed Sensor in the parts listing and a Speed Sensor in the accessories. Which one would it be?
