Hello. I have been doing THM400s and 350s and 700R4s for quite a while but have never done a 200R-4. With those GM trannys I do, I usually pick any core up and rebuild it. If they were set up for wuss motors originally (fewer clutches or weak VB setup) I could just upgrade it easily. However, in reading some posts here, I am under the impression that wimpy cores will remain wimpy cores, unless the VB and governor are completely swapped out. Is it possible to find just any old 200R4 core and upgrade with a shift kit and modifications the governor? Or do I absolutley need to find a Hi-Perf core?
