Default Re: M40 adjustments

Wilma you are correct.

The governor revisions affected the shift points (up or down). I was able to dial in WOT shift points that were substantially higher than stock since I was starting with a pretty lo-perf trans. The shift improver kit is what really firmed up the shift itself as I chose not to adjust the modulator at all. Both things were pretty low buck modifications I could do myself that I felt really worked well for my application. My goal was to duplicate as close as I could the performance of an LS6 M40.
