Good Day All!

I am resurrecting this post as I have not been able to rectify the problem but I have more data. :-)

1st off, I did not realize I have had this issue since October of 2014...

I checked the tranny fluid level per Diesel911. It was a little on the low side but still above Min. (Thanks for the advice Diesel911!)

Today, I drove it with my Mityvac connected to the vacuum system. I specifically put a "Y" in the line going from the BFS (Blue Flying Saucer) to the transmission. Although the level would fluctuate, it never went below 10".
As I understand it, the vacuum level should decrease all the way to 0. I did not even get close to that. Does that mean my BFS is shot? If not the BFS, where should I troubleshoot next?
Thank You All!

PS - Cruise Control is no longer working either. Is this related?
