hey people, sorry to be flooding this post with my curious questions, but when i am going slow (45-50) or somewhere in that range, and i floor it, it really seems to shift really rough when it shifts. is this normal? 302 with a 4r70w. would merconV really help, or is this just a chararistic of a 4r70w? when i get up to about 65, and floor it, it only goes down 1 gear, and is smooth as butter. o well. THANKS!!!
