I would check the air pressure after the regulator. It could be low.
Regulator pressure should be between 75–85 PSI.
The syncro could be on the way out. I would not take the chance.
It could shut you down on the road.
There is a troubleshooting procedure for the air system on page 33 of the manual.
A good place to start.
