I received this via email and don't have time at the moment to formulate a response. Somebody please give it a go.

"I have a 85 300TDT that seems to have a vacuum issue. The trans thumps when I slow to a light, otherwise it shifts fairly normal. I noticed my brake pedldle is also a bit lower than normal. I have a mity vac and pulled 10 lbs on the vacuum line which held. I'm not sure where to start. How do you test the vacuum pump? What should it be. Thanks, Brian"
