I have the push button 4x4 on my 97 z71.

My 4x4 works perfect. But engaging into 4hi has a little clunk when engaging. And the 4low has a clunk engaging so powerful it rocks the truck(feels cool) its loud. Something to be concerned about? No noises after that, just engaging and disengaging.

In gear I can only go into 4hi and you have to be in neutral for 4lo to even bother trying.

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
