How long did your Allison transmission last in your Duramax powered truck before you had trouble w/ it?
I'm asking b/c I'm looking at buying a high mileage (198k) 2500HD.

06 with 190,000 miles. Not one single issue. That damn truck is bullet PROOF!

Not a pickup, but the ones in our ambulances are good for 80 or less....of course they're loaded to the max and we keep our foot in the radiator most of the time. I would imagine 80k ambulance miles translates into a whole shit ton of regular miles...

Mines in the shop now 42k. When it's cold out only 4th and 5th gear work. I think they are replacing the shift solenoids. Yesterday it was -40 degrees at work. Steamboat Springs Colo

Considering I didn't pull the dipstick out of my 01 F250s 7.3 transmission until 200,000 miles I find all the talk about Allison’s reliability laughable!

And I find your lack of vehicle maintenance knowledge and skills laughable.

My buddy has been looking for a dually to replace his SRW F350. So he calls the other day and asks me what I think a Duramax/Allison is good for mileage wise. Says he found one in the paper that he thought had to be a misprint so he called on it. 06 2wd dually crew cab loaded. $8500. I told him they ought to go ~300k without too many issues. He laughed and told me it was no misprint this thing had 636,000 miles on it. :rolleyes:
