Vacuum modulated shifts vs computer controlled How much better is having vacuum modulated shifts rather than computer controlled? I'm not pushing that much power, but someday I may upgrade to a stroker (currently have heads/cam). I'm trying to decide which built tranny to go with and if I should opt for this.
Thanks.

I would never buy a "built" 4L60E that was not vacuum modulated. I am spoiled now that I have it. 
Biggest difference I noticed was the lightening quick downshift response vs stock; also seems to upshift a lot quicker at WOT.
Also, many people have had issues with the PCM not supplying proper line pressure thus causing premature wear issues. The vacuum control removes this problem.

If I did it again I'd opt for a TCI Trans Com and control the shifts threw it.

Edit is NOT remotely as good a a T-Com...The way it controls the trans is much more superior.I've seen trannys do strange things with EDIT but have NEVER seen a T-Com not shift or LU a trans exactly where u set it at bro.
I've had it so I'm speaking from experience....
