Upgrading my th400
So I've decided to upgrade my tranny. I'm replacing the direct drum with the stronger 4l80 drum with the good sprag. I'm also running a Tbrake so I need the bleed hole behind the piston. The drum has what looks to be a bleed hole already, is this really what it looks to be here in this pic? Was tired of short shifting to be easy on the roller clutch.
