Kickdown with transgo tf3

Ideally it's best to have a converter built to your car's specs, not just pull a number out of the air.

And to ad, if you're going to the TF-3, I believe that converts your VB to full manual. That in of itself increases the line pressure, eliminating the need for the throttle pressure linkage.

Your shifts WILL be neck snapping, not really, but they will be very firm. :D
