Tranny Mods for '04-'07 Trucks

[Galaxy]

What mods are available for the NBS tranny, be it either mechanical or electrical??? This truck has a 4R75W tranny, correct?? How different is it from the 4R70W? What mods are you guys doing to improve tranny performance?? For example, Factory Tech made a valve body for the 70. Do they make one for this tranny? Or are you guys doing some type of electronic control to improve shifting, etc?? Which one works best? I've never done anything electronic to alter tranny performance, just the FTVB in my '02, and love it. Made driving my dads '07 feel very 'soft'.

I know for a fact that Troyer Performance has something in the works right now for these transmissions. Very worthwhile in my opinion.

I have talked extensively with Mike and I have to tell you that he has the best understanding of what it takes to get things right on these trucks in the things that we talk about than I have even come close to seeing in anyone else.
