Losing air 5-6 psi per minute while driving

Mine does the exact same thing and it’s a 13spd manual. If you figure it out please post

 

Why didn't you save time and do that first? We're talking about a warrantied truck, right? You said it's a 2018. Stop wasting your time with the deadbeats at TA on your nearly new, high tech truck.

 

Iv seen a bad turbo actatior cause similar symptoms

 

Air leaks when start and run engine shut off no leak any one know Wer problems

 

Same problem right now. 2013 cascadia. I’m going to see if a new governor does any good. My compressors cycling every 3-4 minutes, but only when engines running.

 

Probably something to do with air suspension or air on the transmission. You guys realize your compressor is always operating as long as the engine is running? The air is just either being redirected back into the intake or charging in the tanks.

 

Thats not exactly right. Yes obviously the air compressor is always turning but when its unloaded, not demanded to build pressure, its not making any compression, i believe both the intake and exhaust side are held open thus its just turning freely without any resistance and slightly perhaps increasing its life. I think

 

Hello
Just now i had the same problem with my 13 speed Coronado
It was loosing air like 20 pounds every 2 minutes
Really really huge leak
I spent 1700$ on repairs and didn’t fixed nothing
Last night while driving in La on 10 through construction i was driving for about 20 minutes in low gears and had no leaks at all
As soon the road opened I switched to a higher gears it started leaking right away
Also didn’t leak in even gears ( 6-8-10-12 ) only leaks in add gears
I pulled over right away shut off truck put my gear in 13-th gear and released breaks
Went under the truck and find out that a tiny blue air line that is for high gears located on top of the transmission got a whole in it, it was rubbing on something
I cut it off with pliers used a quick connector and fixed my air leak
It was giving me a headache and costing me money
I hope this will help someone
