New encoder motor is in and works like a charm. Thanks all.

So my part came in! I am going to change the Diff fluids as well as the tc fluid when I crawl under this thing. What are the best fluids to use?

K so update... The encoder motor is defiantly all jacked up! Hey it's cheaper then replacing the entire transfer case. Roadie thanks so much for explaining the two sounds. Soon as I new what I was listening for it was a night and day difference. So today it would not engage 4LO. You could...

could be cavitation form air in the pump if the coolant system was not primed after it was put back together. Also any time I remove a head I change the oil before I start it. I have seen antifreeze make it in to the cylinder when removing a head. Could have also caused the white smoke.

K most of my experience is wit LT1's and LS series but my money is on the a/c pump. Do you have a mechanics stethoscope?

Thanks all

Hi all, I'm new here so I will try to be brief. I have a 2005 Trail blazer LT with a straight 6, all stock no mods. A few months after I bought it the 4WD light started coming on and going off. During a snow storm my wife put it in A4WD, it ended up getting stuck in 4WD HI. It released when...

Hi everyone, I just joined looking to pick up some information and maybe help some other where I can.
