WWWeeellll.... My predicament was that I had the engine running in reverse, park brake locked, at 28 degrees with a moderate easterly wind. Of course the engine will not shut down unless in neutral. It would not shift out of reverse. In the past I had manually moved the transmission shift input from the engine compartment but couldn't get it to move.  If I raised the back of the coach I could see the shifter through  the wheel well but couldn't reach it. I WILL NOT crawl under without cribbing. I found a 5' long wooden dowel in my shop and was able to reach under from the back of the coach enough to manually push the linkage and get it into 3rd....Good enough . I drove ahead halfway down my driveway and backed into my shop perfectly in one shot. It still would not go out of reverse. I turned the key off, found my trusty wooden dowell and pushed the linkage out of reverse , shutting down the engine.
At least it is in the warm shop. I know what one of my winter projects will be....
Thanks for the responses guys...I may need to talk to Michael about it.

Finally, something I know a little bit about!
I just rebuilt mine. The guys at :

T. H. Anderson Pump Co., Inc.
(800) 594-7867

were absolutely amazing! They had the parts in stock!

'T' spent 30 minutes explaining how it works. They sent me all kinds of information, helped me identify which one I had, and rush shipped me the parts I needed.

When mine started acting up, it would shift down fine but would not up shift until fully warm. I made a stick with a hook on it to push or pull the transmission lever.

Then it got where it wouldn't up shift at all & sometimes, the shifter didn't want to move at all.

The issue was water inside the lower cylinder. I suspect a previous repair wasn't sealed properly.

The repair wasn't difficult, just a bit tedious. . . .
