Detroit transmission


Recommended Posts

I drive a '20 Cascadia with the 12 speed detroit in it. Been trouble free so far. Just don't try and take off fast. Not the freightliner tho... what junk.... I'm 6'5" with marginal knees, trucks a day cab, I wouldn't be able to do what I do without autoshift.

I will give them a thumbs up. They designed it with no egr  cooler and only passive regen. As far as repair most things have gotten to be unit replacement.

I agree. Only passive regen and no EGR cooler is a positive. 23 to 1 compression ratio should make it a good cold starter and a fixed geometry turbocharger means less moving parts to get caboned up and stuck. I wonder if their wiring harness issues are resolved.

They will use twice as much def per mile though and guess where all that comes from….China
