Default Speedometer question
I have a TKO 600 transmission and an Autometer speedometer. The speedo cable plugs into the transmission case near the back and has a gear that engages with something inside the tranny. I am going to change to a different rear end ratio (3.15 to 3.73 or 3.91). How do I get the speedometer to read correctly with the new rear end ratio? I'm guessing that I need to change the gear on the end of the cable. Correct? If so, how do I know what gear to use and where do I get it? Thanks.
