    Well that's not smart. All of the information is there, just need a way to compile it.

    I'm using a 4L80E and there is "Input Shaft Speed" on 4L80E, but no Output Shaft. I only have [Speed], which shows as MPH. I used this to convert MPH to driveshaft RPM.
    ([Speed]/60)*(5280/((27.7*3.14159)/12))*3.70
    27.7 is my tire height as it's entered in "Tire Diameter" in the ECU, and 3.70 is my axle ratio. If there was an easier way, please let me know. LOL.
