Cheetah shifter? I love mine but not sure it would work with an air solenoid? Likely I'm just not familiar with that type of setup as it's well above anything in my et world!
They make a kit for the Cheetah shifter for the 1-2 and the 2-3 shifts. But it's only available using air. That's why I use the Pro Ratchet shifter because you can use electric or air. I like electric myself
