MegaSquirt has a "MegaShift" TCU for standalone operation ... but to my knowledge no one has made it work even with a five-speed automatic. Still it is supposed to handle up to 8 forward speeds but has only been verified with 4-speed automatics
Some guys have made the GM auto work with simple push buttons (using no controller) and not paddle shifters but literally one switch for each gear, like the Nissan there is a single solenoid for each gear. however that method does not provide for failsafe (failing solenoid) nor does it control the line pressure which I would guess on the Nissan is a PWM solenoid
If you go back to the early 1990s the Nissan four speed automatics are conventional -- no need for electronic control TCU -- as they only have electric lockup for the converter
