Hi. I hope there is someone who can answer this!!! I have been searching for a long time. I have a red '99 chevy truck z71, and a 01 forest green tahoe z71. The otherday, I was testing the four-wheel-drive system, since I have not used it latly. I have tempraly missplaced my owners manuels and I forgot how to put it in neutral from the autotrac controlls. (It has auto 4x4, 2 hi, neutral, 4hi, and 4 lo.) There is no button for the neutral. Can anyone help me???
