I was just researching options for transmissions if I happened to go to a manual in the '97. One obstacle in going with a later model transmission is the incompatibility of the OSS with the factory speedometer. I know the Dallas Mustang Speedcal Extended Range and something from Ford Motorsports used to be options, but it looks like those have been out of production for many years. I was just curious if anyone was running a later model transmission and what they did to get the stock speedometer in the car to work properly.
