ok guys u pulled the 4L80e out of my 99 2500 4wd to overhaul it, i have got as far as i think the 2nd or 3rd pack, but the tranny is completely different from a 4L60, the part where im having trouble is there in a assemblely that has a bolt runing through where the valve body goes thats held in place, there actually 2, 1 bolt is towards the front of the tranny, the 2nd is towards the rear, im having trouble with the one at the rear, its a 12 point bolt if i remember right, i have removed it like i did the 1st one but the assemblely will not budge, is has one of the steel plate things made onto it and has a snap ring lock ring w.e u wanna call it behind the steel plate. any help on geting this out?
