Flat plate under the trans mount has 2 screws, remove them and the cover plate. Remove speedo gear housing retainer bolt, mark the speedo housing rotation as it is eccentric before prying it out. Remove the tail shaft bolts. Spread the snap ring under the previously removed cover plate, remove the housing. Pay attention to the location of the rear band anchor parts before pulling the band anchor shaft. It is only held in by an O-ring and can be worked out with needle nose or screw driver. Make sure to fill the cavity behind the low band shaft after reinstallation to prevent a leak later, I use a putty knife before tail housing reinstall.
