Richard,
I only hear it when the coach is aired up. There is no air connection from the shift actuator to the trans. I noticed it at approximately 80 degreesF. I am almost sure it is inside the trans pan. I'm trying now to determine if it is something I can dig into or take to an Allison dealer. It seems that air modulators are used when an air accelerator pedal is installed. Mine is an electronic accelerator pedal.
