Vacuum Modulated 4L60E?? MY tranny is being built as we speak and the builder recommends going vacuum modulated so that the computer isn't pulling line pressure during the shifts. What do you guys think? I plan on doing it just because I trust his judgment, but I'd like to get a little more info on it.
my brother has it done on his car, and it has worked great, the only thing is that your check engine light will be on due to the computer not controlling the line pressure, but you can delete it with any tuner program. his shifts are very firm and it seems to respond better under full acceleration. hope this helps some.

I have a few vacuum modulated 4L60E's in the nines, running very successfully. I have been using the vacuum modulator on 4L60E's for over 10 years very successfully. There has only been one case that the vacuum modulator did not work out very well for me.

I'd say that you have no clue what you are talking about... Maybe if you made enough HP to kill a stock tranny, you'd know that the vacuum mod is the 4L60e's best freind. Infact I don't consider it a built tranny with out one.
