Re: Why didn't Hummer go with 2WD w/selectable 4WD?

I think I see. Thats effectively a gear driven 40/60 except its through the chain. Then shifting into 4H moves the shaft, relative to the planetary, to a one-to-one drive(?) I would have thought they would have left street mode open with 50/50 and 4H lock 40/60 for OR.
It would seem to be very easy to design a 2WD select for this T-case.(?) |
