    Yea, the average price of a home here is about 10 times the price of a 2001, 2500hd, crew, Duramax, Allison, 4x4 loaded. Then you have to pay $1.85/gal for 87 octane reformulated fuel, and drive on the freeway going 25 mph. Why do I still live here?


    Autotrac...I still think we are pushing the front axle all the time. Even though the hubs are not locked the axle still turns.
    The shift on the floor does not turn the front axle when in 2hi, the autotrac does.
    Is that lowering mpg? I don't know.

    I have owned 4x4's since '75. This is the first time I've had a pushbutton or auto hubs.
    The Autotrac will be nice when there is snow and ice and dry pavement.
    I would drive with the front hubs locked and put it in 4hi when needed. Problem is you can not put it in 4hi as fast as Autotrac can, so I believe it is a safer system.
    I use to cringe when my wife would drive my truck to the store in those conditions, hearing the tires "walk".

    But now I'll cringe seeing her drive my new truck, just because it's new!

    Nowadays all 4WD system wether they are on the floor on a dial all either does is actuate a solenoid that engages a coupling sending power to the front wheels.

    Well, when I pull the shift lever into 4wd it also engages the front driveshaft and causes it to turn.

    When I'm in 2wd, the front driveshaft is free and can be turned by hand.

    Pulling the lever also engages the couplings and conects the front wheels to the axles.

    I don't know all the mechanics on the pushbutton 4wd, but on the manual floor shift,I was of the understanding that it still mechanically engaged the transfer case, but at the same time, the solenoids locked in the front hubs. My old truck, a 93 K-5 Blazer had the shift on the fly and when you first shifted in, you could feel the transfer case kick in but it took a little time for the front hubs to lock in of which the 4x4 light would come finally come on. That was the old method GM had before solenoids on the hubs. I think it was some heat activated device that once the transfer case was disengaged, released the hubs, also. Any GM service techs to fill us in? And previous to that truck, I had an 83' GMC full size Jimmy that had manual hubs, but it was an option for the automatic hubs that you had to back up ten feet to unlock once the transfer case was disengaged.

    This truck was made for snow. I got plowed in at school GRRRRRRRR damn plowers. The plowed a box of snow around me probably to see if i could get out. With ease i did.

    You should see my dad driving his 2wd S-10 slipping and sliding not able to get up the driveway heheh

    Hello,
    I am supposed to take delivery on a 2001 Silverado LS Ext Cab 2WD 5.3L in about 2 weeks. I understand that all new motors have a certain amount of contaminants and pieces of metal which get trapped in the oil filter. I am planning to switch to 0W-30 Amsoil and the technician there recommended that I run the factory oil and filter to catch these contaminants and metal pieces and then change out the oil. A friend of mine suggested that maybe I should run the truck for a 1000 miles with the factory oil and filter and then change it with regular oil and filter and go another 1000 miles before going to the Amsoil. What do any of you think?

    Thanks,

    You should stay with the weight oil that the owners manual states.The reason is that the oil ports are design to flow a certain amount of oil changing the viscocity of the oil changes the amount of oil and more oil is not better.You can change brands of oil and oil filter though.

    I like the HD. But I don't want to do the special order thing. All my dealer has in stock are the 6.0L and 8.1L w Allison. If I do something, I want the Duramax. I'm not sure a new one is any better than what I have. So I'm in no hurry. I want to pick one off the lot. Easier to wheel and deal. Still love my Silverado, 5.3L, 4.10 locker, longbed, 34 gallon tank. THE TRUCK

    The owner's manual allows for the use of 0W-30 especially if it gets below zero which it does here.
