-2 high -4 high +4 low Will not drive in any other setting.

In 4 low, I think Park still engages... But, when not in 4 low it acts like I have the transfer case in neutral... Even when I move it all the way forward to the 2 wheel drive?

T-Case gonna have be removed and opened up to see what's damaged!!

Thank you for answering... Unfortunately, I am not that handy automobiles. So, I may need to take pics and have someone that knows what to look for view them. I wonder if it is possible to add them here?

No, unfortunately this site won't allow it!.. Check out YouTube, probably find some very useful videos!!

Thanks again, much appreciated! Cheers!
