2014 Freightliner Cascadia error codes, need mechanic in KC

Just check that tiny filter in driver side of transmission, it is inside a small hole but u can take it out and clean it with carb cleaner

 

Yes it dose.

 

Hi there Boss,

Cascadia 2015 Auto trans.

I have this code piping out and going a way
SPN 520970. 7

When we stop, is staying stuck in gear and truck shots off, and then drives fine but that code will pop up now and then. Any

 

Dirt got in deep in transmission where air line enter transmission,
I spryed w40 inside transmission at air entry few times and with long wire brush. You might need doing it few time now and then.

 

Thank you Man,

We are bringing truck back on Friday, will give it shot
