Here's something new with my '04 Z71 Avalanche: The Autotrac won't go into Low Range....Auto 4 works, 4 Hi works. Push the 4 Lo button, it flashes for
20-30 sec and goes back to 4 Hi. Tried it moving slowly and stationary in park.....am I missing something? Temp here has been about 15F (-10C) but the transfer case is fully warmed up when trying this. This is my first experience with electronic 4WD engagement.- posted
