A little update, I ordered a linear actuator (4 inch stroke), a control board, a position display and a power supply. Locally a bought some components and built a resistor circuit and switch set up to control the position of the actuator. I was only able to find a 6 position switch in the style I liked so I will be limited to 6 positions. All are adjustable, so for now I will have P,R,N,D,3,2 with no first control. I could give one of the other gears if needed (maybe neutral). Anyway I have tested the control circuit works good. I'm still waiting on the other parts to arrive. So this little silver knob is my shifter control.
