I will post back with the manufacturer and part number.

Thanks, I appreciate that. I know I have a few leaking seals that could take care of.

For all those interested (or searching this subject months from now) it is a matco tools #9648. Took about 5 minutes. Just knock the threaded end of the remover tool into the seal and give it a couple turns to "bite" into the old seal. Use the bolt provided as a press to pull the old seal out that is now attached to the threaded end of the remover tool. Then use the installer to knock the new seal into place. Nothing to it.

No clue... That is why I spent $40 on the tool.

I know on a th400 without the tool you drop the pan unbolt the shifter linkage inside and remove it from case use a pick to get the old seal out and to put the new one find a deep well socket that is close to the same size as seal to tap it in.
