727 shift shaft seal replacement

TrailBeast said

I have a 3 inch section of allthread with washers and nuts to pull the new seal in.
Of course the pan and valve body have to be off to use it.

One of the best is the seal puller 70Duster440 posted. because it can be pulled by only removing the shift and KD levers.
One big drawback to that style is having to drop the rear of the trans down so far to be able to tap the new seal in.

That is why I would just as soon pull the pan and valve body and pull the new seal in from the bottom.
Once the valve body is out of the car it's a lot easier to do the KD shaft seal.

I watched a YouTube video with a guy using the same removal tool that 70Duster440 mentioned, and after 45 minutes with this tool the guy gave up and just used a screwdriver and pried it out. Watching the video he couldn't get the removal tool down inside the seal to pull it. I made myself a small hook with a handle and the hook is thin enough to get between the seal and shaft so we will see what happens. I don't know how mechanically inclined the guy in the video was so I really can't judge how good the removal tool is, but for $30 bucks I will try my hook first.
