yeah, this is the first 80e I've been inside of. The concepts are the same with all transmissions but things are done differently internally in the 80e than the 60e. The parts look very solid. I can't wait to feel the shifts of this big beast. The current 80e thats in the truck right now was pretty nice, can't wait to feel the difference with the shift kit, vacuum mod and 3600 rpm 9.5" stall converter.
