On a side question, I've owned three Blazers ('88, '89, and now this '99) so I know a little about them, but I will be the first to admit I don't know anything about this fancy Auto 4x4 system. This is 'supposed' to be the same system as the Olds Bravada had which is full time 4x4. Is that true? I thought it would require a third center differential to be a true all-wheel drive. How does my system work? Is the differtial engaged and not the transfer case until it needs it? I read somewhere that the transfer case uses clutch packs to accomplish this. When it is working the system is so smooth I can't even notice it, but I would like to know what is going on 'down below'. Before anyone asks, no, I don't ever use it when it when the road is dry.
Thanks, John
