Hmmm.

I just typed this very information here; the same time you posted your question.

The fourth gear switch on the 200-4R is normally closed. You can, however, get a normally open pressure switch from a 700-R4 application.

I'm not sure what you're working on there but you can usually achieve manual lock-up through the ALDL connector under the dash on a factory set up.
