Cascadia?

Not a lot of high miles out they yet. I think they have 750,000 miles warranty but sounds like they are expensive to repair of that even possible. People can replace the clutch,I read it was about $4,000. I read something about Detroit does not sell part for the transmission. Not sure if that’s is true.

kinda like Volvo I shift not sure they repair the transmission if they go bad.

 

I’ve got one,670k miles, no trouble.
I’d advise changing oil/filter in transmission ever other year.

I’ve had the truck for around 4 years

 

I've heard a few people say that the DT12 has very few parts available to purchase and if it packs it in, new transmission time.
