Not to be rude or anything but I have taken few transmissions apart and most of them look the same on the inside, maybe few little changes. I dont see why I cant put these gears in bymyself. It sounds like these guys just do magic on the cases, if there is some special custom or whatever way they do it, I am sure just by looking and examining everything I can put these damn gears in. Anyone has had gear clusters side by side and compared them? Or should I just keep reading and dont put my .02 cents in?
