Uh... i just noticed that my tranny is put in viscous free mode (bolt through center hole) Is there some reason that the person who had the car before me might have had it in this mode? Its been fine the whole time ive drivin it, would there be any reason not to put the bolt back in the top hole (viscous mode)??

Put it back in the top hole (viscous mode) right away!!! :ugh:

The BGB says: [Quote]
Viscous Free Mode (middle hole)
This mode cuts off the driving force transmitted from the center differential to the control coupling, and makes the center differential free.
CAUTION: Never use this during normal driving. [End quote]

Ya, thats where i read it to begin with and it made me check. Then i found what i wasnt expecting.

Does anyone know exactly what this does? It sounds like it would put the tranny in neutral. It could be possible that somehow i am in the right mode, but the lever got moved? I guess find out which mode it is when i can get back to my car and shift the lever through the 3 options.

AFAIK, it's to switch the car to 2WD mode for dyno or other testing.

I know what fwd mode is for, but not sure about the non-viscous.
Well, i figured out my car is in the right mode, but for some reason, the shifter lever must have been taken off before and just not put back on the right way. All is fine though.
