I have a 1994 Jeep Grand Cherokee with the 5.2 L. and it recently has started this relationship between the speedometer needle jumping from 30-110 and many other weird combinations. Anyhow, as the needle jumps around the transmission seems to react with it. I was doing 55 on I-5 and when I finally got to speed the needle kept jumping up to 110 and back and forth and as it jumped high the transmission would down shift like I was hitting the passing gear. I was thinking that maybe the speedometer cable has gone bed but I never thought that the two effected one another. Any ideas would be helpful.
