If trying to use a TT trans in an NA you would either have to grind down where the starter mounts so that it could engage the smaller NA flywheel or just use the TT flywheel, which could be used with only a TT clutch.

Jun 29, 2018 · TT and NA speed sensors are different due to the difference in final drive ratios. TT has a larger clutch and flywheel. Other Radiators (and fan shrouds) are totally different.
