but doesnt smooth shifting compromise the speed of the shifts? Say if one installed the Trans Go kit in thier cars, the car would shift firmer and faster that it had before. The Trans Go does this by modifying the pressure in the transmission fluid (or some fluid) right?

But as you continue to drive with the Trans Go installed, wont the a604 learn that the pressure is too great, then adapt itself to the new pressure, and finally return the the old slower smoother shifts again?
