I have such transfer case in my Montero SUV, but never understood how really it works. I can speculate that the gears are always in mesh like in normal gear box and engagement is by "electric clutch" similar to A/C compressor clutch. Yes I can engage/disengage transfer case without taking foot off throttle, but it does not happened instantly - only blinking light on the dash acknowledges that transfer case is put in "engage" position, and computer thinks up to as much as 30 seconds before something "clicks" and you can feel actual engagement done (light on the dash lit steady). During that time something going on mechanically (matching RPM?), because it would never take computer to think even for 1 sec about it. Any transfer case experts out there? Victor
