So, the key to the success of the unit is the speed of the tranny's output shaft so that there is enough pump speed to generate enough pressure to keep the cone engaged? Right?

Vehicle speed is not important, just tranny output shaft speed. So the pressure switch is a better choice. Right?



You can use a pressure switch to control it but you will have no control over the GV. Do you really want it to shift into overdrive while you are still in first gear? With a manual switch you have control. I have a reverse manual valve body in my trans. I run through the gears then shift it into overdrive. It's like having a four speed. Around town I leave the the overdrive disengaged.
