Just got done with my trans lastnight.Put new c-3's and transgo,boost valve,conv.I wanted to make sure that i did the c-3 the right way.The steels were not a problem but i wanted to make sure i did the fric right.I installed them all with the slots together i didnt think i made a diff because they spin between the steels.The other thing i was curious about was the main shaft i didnt remove it nor did i remove the planitarys is there anything to align for getting everything lubed properly.I couldnt find a atsg manual soon enough to get my trans done.The transgo,and boost valve were easy would like to double check myself on the rest.
