My vacuum 'profile' is 12"-0" , and I set it several times ranging from 8-15 on the high end with no noticeable effect.
I think if I read mr safety sam's thread again, i am going to freak out. Read it like 3 times last few days. Pretty much talking about 300's, bowden cables, or things I have already done or tried. same for the the Brotherton essay. and the deiselgiant page.
I am considering , for the first time in my life, giving up and takin it to the shop. though this is a real kick in the jimmy.

If you have a Mityvac, just bypass all the controls under the hood and pump up the line to the modulator to 15" and keep it there (run the Mityvac into the cabin).
Take it for a drive and determine if the shift characteristics change with vacuum applied to the modulator directly. If they don't, it's an internal transmission problem and no amount of diagnosis under the hood can solve it.
