I've heard of people filling the case with transmission fluid and
*idling* -- nothing more -- until warm to loosen up stuck rings,
etc. but I would not think this is a good idea and I would not do it
unless my next step was a rebuild anyway.

A couple of changes of Mobil 1 oil will clean out any sludge fairly
well.
