2004 Saturn ion redline
So I have a 2004 redline and I replaced the tranny in it with a tranny from an 07 along with its intermediate shaft from 07. In 2004 the speed sensor was on the intermediate shaft and in some newer years models they moved it to the tranny. So I didn’t end up having a speedometer because of that swap. The factory connecter for the 04 was too short to reach the tranny because it was made for the axle speed sensor so I spliced into the connector added some wire and hooked up the new connecter onto the tranny but now that I’ve done that my speedometer works but it doesn’t apparently at 40mph I’m doing 140 lol the speedometer goes way to high anyone know a way I can fix this?
