i am having trouble with a trans that i rebuilt shifting at higher rpms (between 4 and 5 thousand) at normal driving throttle pressure. this trans was rebuilt with new plates composites bushings and seals. new shift modulator too. i also installed a b&m shift kit,(stage two). i have tried adjusting the modulator, and checking vacuum. but before i dig in to it again, i would like some ideas to look for. this is not the first trans i have done but i don't do them enough to be an expert at them. any suggestion would be greatly apprieciated. thanks
