shifts seem to be better right after a flash, then as its learns how you drive and all the slop from wear it will start to feel not so crisp.

my old used tranny had a 300 rpm slop over at the shifts, so i set them for 5800 it shifted or took the next gear at 6100. now this new tranny is also set to 5800, and it shifts at 5800 cause it new.
