    I was issued freightliner cascadia couple days ago and I am trying to get my optimized idle to work. Whenever I set it my secondary air tank loses pressure and low air warning comes up. I don't believe I have a leak Becouse if the truck is off, it stops leaking. And besides it tells me that it's 84f in the cab, it should just idle anyway. So, is it just broken or am I doing something wrong? Thank you

    Call up the Gra Gar in Lithia Springs. They're the most helpful number for this sort of problem.

    Rubber seal on trans is leaking inside trans. it will leak while you are driving in hi range so it needs to be fixed, the temp. sensor may need to be replaced to keep you idle in this cold weather.
