to change the noids no, but im saying if its no that bc the valve body is bad or something its easy to pull

if you have all the gears when the fluid is cold i dont think its going to be a noid. i say a problem with the valve body, but im not a tranny guy. i can put a stall in, pull servos, change filters, an pull a valve body to
install a new seperator plate but i cant pin point your problem.
