Ok but im not wanting 4l80e lol i dont race this truck its a daily driver im happy with the performance and fuel economy of the stock 4l65e has held up nice till i ripped the teeth off the ring gear do to the guy i paid improperly installing them. I might be interested in installing one in my 98 camaro when i put my stroked ls3 in it so if u have info on that pm me thanks.
