ok on my 92 Roadmaster i have a issue with my speedometer working then not working. i've replaced the speed sensor on the transmission and it still is goin in and out on me. sometimes my Service light will come on but then it goes out and it will come on and off while i drive. i just have a suspicion that the speed sensor wasn't the issue and that the service light has something to do with it. i just wanted to see if anyone has had this issue and what solutions there are.
