Updated the 1st post to include the Pneumatic Tanks Orientation.  Transmission Air is what I was told but Steve (Capt Gizmo) thinks it may be trailer air which makes more sense.  I may have misunderstood the terminology.

Thanks for putting this out, Jim!

When I get it up on the rack at Newell in a couple weeks, I'll discuss it with the techs and see what we come up with.  I love a good mystery, unless it's on my coach!  LOL
