So a rebuild of the guts required then. How would one recalibrate the speedometer, or do you even have to if speed is taken from wheel sensors?

I figure the following:

4.1 approximate Ratio relationship MT/AT: 1~=1,2<2,3<3,4>3,5=4,6<5,6<6
3.727 approximate Ratio relationship MT/AT: 1>1,2>2,3=3,4<4,5<5,6>5,6<6
