Good luck getting it fixed and keeping it fixed. I have a 2005 Silverado Crew cab with 55000 miles. I replaced the switch on the transfer case twice the dash switch once and the control module for the 4x4 and mine is still putting itself into auto 4 wheel drive when I start it. I have also had to replace the heater control already.
I would not recommend another Chevrolet to anybody. I am almost ready to trade off for a Toyota or Ford. This is the worst vehicle I hae ever owned.

auto trac 4x4 problems by chew36

i have a 2000 chev with the auto trac transfer case in it, the clutch inside the transfer case has been burnt up and now when i put it in 4 wheel under a load it doesn't spin the front tires. It is a 500 dollar kit to fix it i am told, i am also told that i cannot remove this transfer case and replace it with a manual floor shift one due to the computer. Is this true? If so what does it do to the computer, just bring a trouble code up, or does it actually do something to the truck? any info would be great.

Like everyone else, my 4x4 Tbox is acting up.Does anyone have a punch list to trouble shoot the probblem?I dont want to just start buying parts.I fix elevators for a living so using meter is no biggy,also own factory manuals,And have spent a good part of my life twisting wrenches.

Z71 vs. Z60 vs. Z85 by estampley

Can anyone tell me the real differences between the different suspensions offered by Chevy on the 2007 models. I know the Z71 has heavier shocks, etc. But I am mostly curious about the Z60. What exactly does "performance" suspension mean? I am about to order a new truck and will mostly do road driving but will occasionally get off road. Will the Z60 be able to handle that? I do like the 20" rims but don't want to sacrifice toughness to get it. Thanks for any advice.

I'd like to hear some insight to that as well, I recently ordered a new Silverado and opted to go with the Z60 suspension but I haven't been able to find any more detail on what the "high performance" really means.

4wd and steering questions... by billwfriend
Dec 07, 2006 (6:59 am)

I'm borrowing a family members 2002 GMC Sierra 4x4 reg cab short bed (I think) with 81k miles and the 6cyl engine for the winter.
 
Up to what speed can I switch between 2wd and 4wd high?
 
The steering is a little loose on center... I can waggle the steering wheel a few inches either way on center without the vehicle veering left or right, is this "loose" steering normal with these trucks? I used to own a 99 Ford Ranger and the steering was alot tighter...
 
Finally, there's a little shimying in the steering wheel at cruising speeds... the truck was aligned a few months back, so I guess that could be unbalanced tires, bad tire pressure, or that it needs re-alignment right?
 
Thanks!

Error code: 0323 T-Case Lock Circuit Low
Parts Repaced: Dash Switch and 4WD Frt Axle Actuator
  
Current Symptoms:
1. Defaults to 4HI after I switch the ignition on 5 sec off 5 sec then on 10 sec.,will also switch to Auto 4WD.
2. Depressing dash buttons runs 4WD Frt Axle Actuator with whining then vibrating grinding noise at end of cycle. Acts like the actuator is trying to shift gears but overloads, then shuts down when trying to switch to 2Hi or 4Low.
  
I Checked fuses, left side drivers door and ATV under hood, OK.
  
Low Fluid level possible ?
