Hey guys. I have 1999 mustang GT that started its life as an automatic and was recently converted to a manual. The transmission used was a TR-3650 out of a 2003 Mach 1. Everything went pretty smooth however i cannot get my speedo to work at all. Its still the factory Auto ECU custom tuned for manual parameters. i get a code for the output shaft sensor so i replaced it without any luck. Any feedback would be much appreciated.
