Rolls forward in neutral, locks up rolling backwards??

Replacing the waved ring in the direct clutch is a terrible idea. It will give a harsh reverse engagement that will get old quick; unless you run a high stall converter. If you want a better 2-3 shift, then drill out the 2-3 apply hole in the valve body separator plate as per the TransGo instructions. Double check your work and the same goes for everybody else's work. Air check the drums when you get them back.
