Ok, I did the j-mod but it never mentioned modifying the valve body, just the separator plate. Was there something I was suppose to do to the valve body?
If your going with a kit, go Baumann.
I'm running a Baumann kit in mine and love it so far, nice clean shifts. I've used these kits in a handful of Ford aods and 4r70ws and they make a pretty complete kit...
No... it's all about modifying the separator plate that allows the fluid to move more freely....
