#1 of 384 electric 4 wheel shifting problems by bob7198

My 2000 G M C 1500 electric shift to 4wheel drive works just part of the time. probably trouble with the shift motor at transfer case ? also the right running light burns out every few weeks and the socket is badly burnt.

Sounds like a problem I just had fixed. Turns out the switch in the dash was bad on my truck. It would go out of 2wd into 4wd or 4wd low on its own. Originally thought it was the motor on the transfer case but after having it checked out electronically, it was the switch.

I've been wanting to lift my truck (6"suspension, 2" body) but i notice that a lot of available lifts are for k1500's WITHOUT auto-track 4x4 and non-2 piece drive shafts. I drive a 1995 silverado Z71 ext. cab with the 5.7L engine. i haven't gotten underneath and looked due to a tight schedule so i have no clue what to look for and i'm guessing that its probably a specific year range that those two things fall into, can anyone possibly tell me what year or if my truck even has those things?

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.

#6 of 384 auto trac 4x4 problems by chew36

Oct 19, 2006 (8:47 pm)

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.

#9 of 384 Z71 vs. Z60 vs. Z85 by estampley

Nov 10, 2006 (9:23 pm)

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.
