    Does gm not offer a plow prep package with the diesel engine and Allison tranny? i went to the dealer today and none of the diesel's had a snow prep, but ALL the 6.0L had them. i would much rather have a diesel than a gas.. whats the deal?

    Hey Iam working on the answer to your question, but unless you MUST have that truck right now, then you should hold out to January. The Duramax will have more horsepower and torque after the first of the year. The engine RPO Code will be LLY. I have a friend who is a truck manager and currently all models that they are ordering to come in after Jan have this Diesel.
    Hope this helps, I would hate to see a man spend that much money only to be disappointed a couple of months later. These are the new figures

    I got this off of gm-trucks.com and a member there copied this from The Diesel Page website:

    The bulk of the '04 model year powertrain changes won't be in production till sometime in January.

    Here's a brief rundown of the new LLY Duramax

    1- Scalloped valve covers that position all fuel return lines to outside the engine. Should solve nearly all fuel/oil dilution problems.

    2- New Garrett variable vane turbocharger - better low speed response - better high speed response.

    3- Somewhere between 340 and 360 stock horsepower. The new turbo is responsible for most of that gain.

    4- The added power will only be available in gears 2 through 4. Power will remain at 300 for 1st and 5th.

    5- The Allison will get a freshening to handle the increased power. Some of these changes are in programming, some are in hard parts.

    I have no idea about these changes do any of you all?

    Yes, you can get a Diesel and a plow prep package, but you cant get it with a crew cab in the 2500HD or 3500. You can get it with a regular cab or extended cab. I think it has something to do with the GCVWR but if you did want a crew cab I have seen people who have done it.

    On a side note I was saying at the bottom of the last post. "I had no idea about this, not that I have no idea" Sorry for any confusion. As you will notice the trucks on the lot have the LB7 Duramax not the LYY Duramax.

    You might have guessed most dealers are not going to be real forth coming with the information on the new Duramax cause it would be hard to sell the ones that they have. There will also be a 3500 Single Rear Wheel Model Available after January.

    Hope this Helps :waving:

    snow plow package

    you can get a snow plow package on the regular cab but not the extended cab with the diesel. they dont recommend a plow with the ex cab and diesel but i've got an 810 blizzard with an ex cab and duramax and havent had any problems yet, 75000 miles and plow over an 80 mile radius and run 65 mph with it. just my 2cents.

    Could it be in 2004 that this might be different? I went to www.gmbuypower and it would not allow a crew cab with a duramax and a plow prep on a 2500HD or 3500 but, it would accept it on extended cab or regular cab. I guess your best bet is to check with the dealer.

    ROCK........I did a build yer own at GM buypower too.
    It allows you to get the VYU plow prep w dura/allie.
    On 04 2500/3500 reg. cab or x-cab only.

    But funny tho. I did a buypower search and found NO
    plow prep pkg. dura/allies on the lots. Hmmmmm.........

    And I live DEEP in snow land too....Every other GM on
    the lots had VYU plow prep on them!

    Thats what I found this afternoon. Is that what you were wanting was a Extended or Regular Cab? When I got my truck I tried out a Diesel and I really was in love !!! I just could not justify or afford the extra expense, but I would recommend that you just order yourself one just how you like it. If your going to spend that much money you might as well get exactly what you want :) There is also some talk about a redesigned Chevy in 2005 or 2006. Hope I helped :)

    HD.....Just checked for the heck of it. There is too
    much confusion on VYU plow prep. on certian diesel/
    allie trucks ! Heck ya can't even get plow prep on
    1/2 ton x-cabs or 1500 crews either !

    I know the stealers are a PIA about warranty work
    for plowing related breakage on non-plow prep GM

    I just run a 2500 LD xcab 6.0.......Works fine for my
    needs plowing, towing, and hauling..........

    I only keep them 3 winters and dump them. I get
    the GM employee discount and around these parts
    of NY a 3 yo ex cab 2500 used goes for mega $$$$
    at trade in time with under 30k miles......geo

    FS.........The VYU is the factory plow prep pkg.
    RPO code !

    Easiest way yo tell is to look on the dash next to
    the airbag cut off switch. If you have the aux. light
    button you DO have plow. prep pkg.

    Another quick check is to look at the skid plates.
    If they are plastic no plow prep.
    If they are steel and
    If you have 3 of 4 of them you have plow prep.

    NON plow prep only has 2.............

    Heck now I am gonna have to look under mine to
    count them ! Then check out my buds non plow
    prep 2500 to be sure.................................geo

    Also note....for some reason, the plow prep package is not available in any truck with climate control ac/heat. There will be a climate control delete on the sticker. Why, I don't know. So when you spec a truck out on gm buypower, it will automatically kick out the plow package if you don't check off the climate control delete box...Hope it helps

    I'm sorry, I meant the computer controlled AC. Where you set the temperature to a specific degree and leave it. The truck will heat or cool as needed. I have only seen this on the SLT models with the leather interior...

    I guess my first question would be " What does the Plow Prep Pkg" consist of...?? A bigger alternator...??? A front suspension that will accept the added 900# of a plow..?? An aux. trans oil cooler..... Maybe an engine oil cooler....?

    Good luck......... :)

    depends on what other options you get.......the onlything added if you have a deisel is the provisions for the blinky light, and skid plates. They dont make a gromet through the firewall anymore, you gota drill it.

    It can include different cooling/torsion bars/charging stuff but you get it all standard with the diesel
