I'm new here and would like to apologize if this is the wrong place to ask questions. Okay, I have a 2006 Trailblazer 4.2l 4x4. I started having problems with the 4 wheel drive, so I went ahead and eliminated it by gutting the CV joints and removing the front shaft. Once I got her put back together the motor runs at high rpm when driving and will only shift If I get it up to 4000rpm and let off the gas. Antony have any ideas on what the problem may be? Any help would be greatly appreciated. I'm losing work and I go stir crazy when I cant work. Thank you.
