I think what you are hearing is the air coming back out the intake on a shift. It's a whooshing sound correct.

Sorry this is wrong info
Not Flaming anyone .
The Whooshoing sound is you EBV closing and opening . The EBV closes and holds exhaust gases back to help the engine get up to normal operating temps quicker. If you start it and let it sit when its cold outside it will close and the idle will ramp up slowly. If you touch the brake pedal it will open and then close again shortly after. This will continue until the truck has warmed to normal operating temps.You will also hear the EBV close and open while driving if RPMs are under 1800. If it is closing and opening while driving after warm-up and over 1800 rpm then you have something wrong with either the EBV or a temp sending unit.
Hope this helps, Good luck, John
