    Congrats on the new truck. Can't wait to see pics of it! What type of plow are you going ot hang onto it. A good place for GM Diesel questions is www.dieselplace.com

    Good for you! I second the link to the diesel place...and add www.thedieselpage.com Lots of good info there! The down and dirty...use regular oil of your choice (non synthetic) every 3-5k until break in is over then the synthetic of choice for extended interval. The biggy is changing the rear diff oil, give it about a thousand miles, then load a trailer, or the bed and pull some good loads for extended periods. Then change the oil. You will be amazed at how much crap comes out of it! The locker rear needs a load pulled on it to "set" the gear wear right from the start. (It also seats the piston rings as well!) The diff oil will be clean from then on. I took taht same advice and have changed it twice, first at 1100 mi, lots of metal etc, second at 10000, perfectly clean!! You will love that engine tranny combo. Enjoy!

    Yep, need to get all the casting crap and break in metal out...just be sure you replace it with equivalent oil, GM uses some sort of propietary grape smelling oil, however I believe there are a few acceptable replacements...I used amsoil, and if ever I have a warranty issue I will put GM's juice back in, it is way to expensive for what you get. I can replace the oil 3 times with quality synthetic for the cost of one GM fluid change!

    By the way, I do Auto A/C work, R12 and 134a, have done a few HVAC units but not my bag...

    Also....please let me know if you get the 6 speed Allison, they are reportedly putting them in the '06's but only when they run out of the 5 speeds..I hope you are one of the lucky ones!! Better mileage!

    i dont do automotive, except my own..i do commercial stuff.
    i just went through my 4X4 s10 (87) rear end, replace bearings and seals along with the brakes..i used mobil1 rear end oil 75w/90 full synthetic..
    the stuff looked like water...is this stuff ok for the locking differential?

    yea, i have the allison 6 speed(mw7) tranny..my truck is being built as we speak..:nod:

    on a side note, you know the price of r12 is comming down? im using it when i have a small unit1-3 lbs..i hate the new ****..

    Not sure if the Mobil meets GM's standard that they wrote for thier oil! However someone with more knowledge in that area on one of the two sites linked will definately know!

    Nice to know 12 is coming down, as 134 has gone up 100% over the past 2-3 years! It is one of those "I wish I had bought a ton of that stuff" kinda deals. The last time R12 came down GM was the cause, they released a bunch back into the market that they had horded up!

    Cant wait to hear about the truck!
