    I am amazed how my truck shift now . Since I bought the truck I had a small shutter between 3 and 6 during skip shift and now it's gone. It's worth the money to dump factory fluid and get the amsoil ulv. If you have a 10 speed ford or gm I would recommend
    Bottom Line
    Yes, I would recommend this to a friend.
