727 trans shift tower seal driver, for in the car seal replacement

Hello All
Had a leaking mess under the 727 trans of my 76 D100 build, shift tower shaft seal was leaking.

Decided to replace the seal while trans is still in the truck. Was able to drop down driver's side exhaust pipe to gain good access. Popped the old seal out and made up a special "Seal Driver" that fit the shift shaft well. Used a large C-Clamp with the new Seal Driver to push the new Seal in straight and true. Worked out just slick.


Made up new Seal Drivers, one extra for my Buddy Brian

Finished . . Seal is in straight and true.
Have to use a mirror to be able to get the work done.

Handy Items to have around for the next one that is leaking. Boy do I hate oil leaks . . .
