If you have an Automatic Transmission Saleen Mustang or a GT Mustang, does anyone have a shift kit in it (Trans-Go, B & M, etc....) If so I would appreciate any comments on if this is something worth getting and if so which one or type?? Reliable?? Any issues or problems this may cause?? What about their car programmed with the SCT X-Cal 2's firmer shifts setting?? If you have this on your ride can you tell the difference from just Saleen's Powerflash program??? Does this change the RPM Shift points to give you firmer shifts? Does anyone have a shift kit plus the SCT X-Cal program with firmer shifts??? Can you do this?? Anybody switchout their torque converters and if so do you have a place you recommend??? If you couldn't tell, I hate the sluggish type shifts of Fords Automatic transmissions especially on my Supercharged car!
