My 727 rear tailshaft seal is leaking so I put it on the ramps over the weekend and discovered that I have some slop between the yoke and trans. output spline shaft. Im not that experienced with this trans. but have been told there is a sleeve or bushing in addition to the seal in the tailshaft. I know the seal itself is easily enough removed but what about this bushing? Does it require a special tool to remove and install? If not, any tricks to its removal or installation? Would prefer to do it myself if possible.
