Re: Ultramatic Selector Shaft Seal

Actually it's impossible, within reason, for exterior f***ery to damage the seal as the seal never passes over the end of the shaft. How long since it was last rebuilt? It could just be old. Who knows what someone was trying to do to that shaft. Was Godzilla using it as a toothpick?

As I think you have heard by now, you have to drop the trans to get that shaft out, or cut a hole in the frame.

I have no explanation for that brass area. The shaft should be solid steel. Side note, that bolt is not original, but it matters little. You might get more play, faster.

Any potential leak in the transmission will leak eventually as the fluid gets sprayed everywhere and is good at working into gaps. But that's a reasonable assumption; I forget how high the fluid is in the pan at rest. I know if I was designing something I would try to keep the level below as many sealing surfaces as possible. But the trans, converter, and lines holds 12 qts somewhere...
