I have seen a controller with a manual mode to use paddle shifters or similar mentioned before. It is not going to be snapping fast, but manual gear selection.Not because of expense - was more looking for a manual trans with no pedal.
For basic manual only shifter, just need tps signal to vary the pressure and few switches to control shift solenoids. A simple microcontroller with minimal programming can handle that. Probably few more data points would be useful as well to make sure proper pressure for the load
