no vacuum goes into an AOD. the governors are hydraulically operated in conjunction with TV pressure.
remove the extension housing and the governor valve. rectangular thing held onto the output shaft with a single external snap ring. there will be a metal ball that holds it in place, do not lose it. once removed, it should make noise similar to a marble in a tube rolling around when you shake it. (the valve) if it does not make any noise, then you need to clean it. best to get the book, or if you can remember how it goes back then go for it.
STOP driving it until you get the problem diagnosed and fixed. If you don't stop driving it, you may be in for a total transmission overhaul, if it doesn't have to be done already anyway. At the very least the transmission fluid (and probably the filter too) will have to be changed.
Check the TV (throttle valve) linkage at the throttle body...make sure the fitting hasn't fallen out or isn't loose.
