Ken, it seems to me that if it came out of a 99 5.7 (traditional small block) then it would fit the 96-97's also. I am not positive on this as I am not a tranny guy, but if its true, then I am interested, and could pick it up next week from you as I'm under two hours away. My tranny isn't dead yet, but with 123,000 on it, and behind 400 hp I'm not sure how long it will last. If it wasn't for the aux. tranny cooler I'm sure it would be dead by now!
