Maybe I have not been clear about. And we can continue to disagree; nothing wrong with that.

Because if the transmission is set up correctly, at 1/4 throttle input or less, the transmission will shift hard on upshifts. If it doesn't, you have the modulator adjusted too soft. Above 1/4 throttle input you should notice no difference since vacuum is already bled off. Below that point, YOU SHOULD NOTICE. Exactly the same behavior as downshifting without vacuum, abrupt and rough.
