    In our 2002 LTZ I am having problems with the TB jumping to AWD, 4WD, or trying to jump into 4LO on its own when the switch is in 2WD. This happens a lot at hiway speeds but has also happened just parked and at idle.

    Anyone else have this issue? I have heard several potential causes for this but it has been suggested to me to replace the switch itself.

    Any suggestions would be appreciated.

    I also have a 2002 LTZ. I had this happen only once, when changing lanes on a rainy day. I blamed it on maybe losing traction crossing wet newly painted stripes. It's not uncommon to have the rear wheel break loose on my motorcycle under the same circumstance. I'll pay closer attention to it if it happens again.
