Powerglide self bleed valve body

[r3tracing]

Anyone built their own self bleed valve body for a powerglide that is direct drive with no foot pedal or ball valve. I know they are putting a jet or bleed hole in valve body to release the pressure until you bring rpm up. Can you share how and where you put these and what size of jet you use and what other mods you do to the valve body if any. Or any other mods to the tranny to do this. Thanks in advance.

its easier and probably cheaper in the long run to buy the TCI unit. All the engineering and testing have already been done.

Get the TCI and move on.
