    I have a 2001 2500hd Duramax and I already had to have the trans replaced at 17,000 miles. Very light use, as a matter of fact my wife was using it until her vehicle came in when it happened. The mechanic who worked on it said that a weld broke somewhere and all the fluid leaked out. He said where the weld broke they usually use bolts, but because it was so heavy duty they(Allison or Chevy) welded it. I am not to sure if I am expaining it the right way, but someone might know what I am talking about. Anyway has anyone every had a similar problem. When I asked the mechanic if there were any other trucks come in with the same problem( this was a couple of months ago) he said no. Oh and I got a look at the paperwork for the warranty and if I read it right the trans was like $8,000 and they dont rebuild them yet. See ya.........

    Hey i have a 02 HD with the 8100 and the Allison. They replaced it at 2100 miles. Not the same problem as yours but my wouldn't go past first gear.

    If this thing blows again (like when i'm plowing) i'll probably push it through the front windows at the dealership.

    01 - 8.1 w/ allison
    My truck went in at 5K for a new tranny, then again at 7,400 for another one. The truck would not shift out of 2nd. What a pain, driving 50miles to the dealership in 2nd gear.

    Dealer said that some line in the allison transmissions crack and that crack does not allow enough pressure to create to shift. I don't know a thing about transmissions, but I that is what they told me.

    Now I have about 16K with no other problems.
    Earth - I was plowing when the first one went out. Damn good thing I was cleaning up my own driveway.

    I run a Hotshot company and just mainly haul construction material to jobsites in Alaska. The truck is 18 months old.

    The Sno-Way is junk in my opinion. It is not up to the task of commercial plowing. I busted the A frame on it already toward the end of the season last year. The controller quit working. The valves were not set right right from the factory and had to be adjusted. There is a recall that I have to go in for to get a valve replaced. The up-down cylinder developed a leak and would not stay up. I lost a few bolts that rattled out. The steel skin dents easily. The welds for the brackets that hold the shoes broke. Everything was replaced or fixed under warranty last year so hopefully I have no problems with it this season. I would love to get a new Curtis but I can't take the loss on a 1 year old plow. My other buddy that I plow with has a HT series plow on a Ford SD and his is worse off than mine except for the A frame. His keeps getting a brain freeze and won't go up or down. This recall is for the valve that controls this so maybe it is fixable. I'll never buy another one. I put about 160hrs on mine last winter. It would be fine for a residential owner for his own drive. My plow is the HT series and is supposed to be commercial grade. NOT!

    Ask away if I can feed you some more information.
