Sumbitch... If the 44-44 in my new truck operates as you describe when it arrives, I'm gonna be pizzed. I need the 4WD Auto functionality for winter driving, but I will burn the clutches up in the t-case quickly off-road. Lock needs to be a mechanical (gear or chain) lock... not a clutch/lsd/coupler/etc.
I just found several threads on other forums about the exact thing you are describing.
Thanks for pointing this out. I think.
