Question 2-3 gear hunting th400

I will give you little backstory on what ik of this transmission. it was a "rebuilt unit of craiglist'' he rated it for 600hp . pretty sure it is just a stock rebuild that had had a b&m shift improver kit installed and the spring removed out of accumulator. trans did work shifted really low rpm. fast forward , I installed a Transgo 1-2 kit installed the pr spring, and I think I have the the heaviest spring in the 1-2 shift "blue maybe"I don't remember what I bored the holes in the separator to ? shifted good ( after 2 trys) I mixed the vb gaskets up. figured that out and then it shifted great but still low shifts. so I messed with the governor . ground some off the outer weights and installed lighter one on the inside got my 1-2 at 6800 which is where I would like it, 2-3 is considerable lower at wot but still fine with . my issue is now that I messed with governor I get gear hunt at light throttle cruising . like if it shifts into 3rd and I come to a hill and it bounces back and forth from 2nd-3rd gear until I let out or step on it . once it gets to a certain speed it has no issue. not sure if I need to mess with vb or the governor or if I need to to something else. just looking for some guidance. thanks
