Nathan,

I have been working primarily on low vacuum problems - slow/intermittent door lock operation and loonnnnnnggggg engine shutdowns. I just bought the car about 4 months ago. It has always shifted a bit soft but now that I am resolving the vacuum leaks it has gotten softer as the overall vacuum level of the system improves. I am thinking that the previous owner may have adjusted the modulator on the transmission to compensate for poor vacuum elsewhere. Now the transmission has too much vacuum and the modulator may need to be re-adjusted.

Does that make sense?

Bill
