Shifting occurs through vehicle speed and throttle pedal position for that transmission to operate properly. It also uses those inputs for converter lock-up schedules and line pressure changes.

You'll need to create a way to have a square wave with 8000 pulses per mile to get it to operate correctly. I've seen a square tooth wheel installed on a driveshaft yoke. There was a VSS mounted on a bracket next to it. It worked fine.
