I think an air cylinder with a restriction in the air lines is perfect
for this
application. This is where you want a steady force applied until the gears
engage. You could always use aircraft cable over a grooved drum to
effect a 180 degree movement of the lever. I think a stepper would
have to have a spring or similar arrangement to keep from stalling the
stepper until the gears engage.
