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!
I think a cheetah can be configured to make ONE shift with a air or electronic shift, whether 1-2 or 2-3, I'm not sure.
I reconfigured my 727 cheetah for a powerglide, air probably would have worked well.
