So I early have to find a gear for this unit. It works just like gear vendors wanted it to operate. Kicks in at 45mph and out at 25mph. That way it won't hunt I and out at one particular speed. I took a video of it with a drill on the end to variate the speeds. When the ohm meter buzzer is sounding the gear vendor is off. When it shuts off the gear vendor is engaged. Heres the video.

This is straight from gear vendors website...
The Gear Vendors AutoDrive circuit will keep the overdrive on until you are down below 25mph – this way the transmission can use the overdriven gears at the appropriate speeds bring the ratios closer to you and we have no hunting caused by being in the wrong gear or between gears. Below 25 we know 1st would be the correct gear so then we turn off the overdrive in both manual and auto positions. In Auto it will come back on once you get above 47mph again.
