So my 1969 A727B is leaking at the o-ring, rear band apply shaft, where it enters the trans case. After removing the tail shaft, pan and valve body, can I sneak the shaft out far enough to change the o-ring without removing it completely ?

Push it in. Clean and apply RTV with a putty knife in the pin bore. Works evert time. Doug Doug, just so I'm clear, you're saying not to remove it all but rather push it in as is, clean the area and spackle over the hole with RTV ? -Pete

Trouble with sealing the end of the shaft is the leaking fluid will usually prevent the RTV from bonding well; best to drain the fluid level to below the shaft, clean the area really well and then apply the RTV. Let it sit at least over night before refilling the fluid.

Let it sit at least over night before refilling the fluid. Yep, that was going to be my plan of attack. Should that fail, any thoughts on partially removing the shaft to replace the o-ring ?

You don't need to remove valve body or filter. Just drop the pan, get a long screwdriver, etc, push the shaft out the inch or so and replace the o-ring. I cut the tab off the tail shaft and made a hold down bracket. Seems like I smeared some RTV over the shaft when I was all done.
