Had a shifting problem, air was leaking out the exhaust port on the shift knob, so we replaced the range shift valve, then the compressor since it went bad while working on the ole mack. changed out governor, replaced shift knob, replaced o-rings on low high cylinder. Hooked up shifter and all worked fine. at road test. this morning started truck and air is leaking out exhaust port on shifter again. Can some one help me with this most frustrating problem "Please"
