I installed a transgo shift correction kit tonight. Or the valve body part. A few different springs & enlarging a few holes. It went fairly smooth I think up until I tore the valve body gasket. So I had to order a new one before I can install it back in to the transmission. I'm still fairly certain I burnt up 3-4 but figured I give it a shot. If I have to get a new tranny I'll just swap this vb to it.
