If you've ever removed your MTX-75(I installed my own Quaife, clutch, and axle shafts; so I have some experience here), you'll see there are a few sensors ,but I don't see anything that would make the PCM care whether or not you have 5 or 6 forward gears. The biggest problem I can see is, does anyone know whether the bellhousing and engine castings from the FSVT are the same as the Contour? plus the need for a heavily modified subframe, and custom axle shafts.
