Thank you Bill for the input. It's not the fast idle. There are certain functions that I know will prevent the shifting of gears, one is it the airpressure isn't high enough. The donor coach has an airpressure sensor that goes to ground if the air pressue is adequate and I believe that is wired in to the 86 Newell.
