Hi @natman316. I know this is a very old thread, but I am having the same issue as you have described. Transmission light comes on after a few miles of driving and cannot select past 2nd gear. Ive managed to source to a new potentiometer on a lead time, but just curious to know if your replacement worked over the long term or did you find out if it was anything else causing the issue ( that's if your issue persisted ) Ay info would be great
Replaced my potentiometer three years ago and everything has been great since. Sent from my iPhone using Tapatalk
