Yea, thinking more about my 727, there have been times I had to manually shift into 2nd when the RPMs dropped too much.

In an RE, what happens when the shifter is placed in 1st or 2nd? Does it no longer matter what the governor pressure does?


The throttle pressure (kickdown) linkage would still be required, but would be completely external to the controller.

I would also need at a minimum a road speed input, and either (electronic) throttle position or MAP (engine vacuum/boost).

I think I outlined the logic in my previous post. Basically, at higher engine loads/throttle positions, I can command a lower governor pressure to induce higher shift points. And make that curve adjustable by the end user to tailor to their preferences.
