4L60E Vacuum modulator ??
I am in the process of getting my 4l60e rebuilt. Should I go with a vacuum modulator? What are the pros and cons of going vacuum. I also have LS1 edit. Could I use LS1 edit to make the changes instead of going Vaccum?

Yes, you can use LS1 edit to change the line pressure of the tranny. The edit will allow setting of shift firmness to your desire. I would just get an electric trans built and use edit.
