Leaking 727B transmission

Yep.. why we cheat.. clean and seal!!! Or you can cut the retainer "tab" off the tail housing with a cut wheel in a dremel and then make a little metal bracket to bolt back on and retain the pin.

Cutting the retainer off will get you nowhere. You'll never get the pin out. And if you somehow were able to remove the pin, all the reverse band linkage would fall in the pan. You need to pull the tail shaft, valve body and rear band linkage and to remove the pin. Just seal it as I mentioned. It's not worth the hassle to swap the O ring. It can be done neatly if you work at it.

To get the rear band shaft out the valve body has to be removed. Then the rear band adjuster is loosened. Remove the band strut. Knock the band anchor pin out from the front through the access hole in the case. Take a picture first so you can see how it goes back together. Along with this, the tail shaft still needs to be removed as well.

Thank you for the help, but tranny is staying in the car. I’ll clean up the exterior pin area outside case and glop on the RTV to plug it up.
Thank you Doug.

The transmission does not have to come out of the car to do as Doug suggested, but the drive shaft has to come out and the tail shaft housing has to come off. As well as oil pan and valve body. It would be nice to have a hoist to do this work on.

No hoist. On my back with car on ramps.
