I've had this 2014 5.0 for a couple of months and am beginning to think the transfer case is 'no more good'! I was using it to drag a downed tree in low and it worked fine I was done with the heavy stuff so switched to high, steep hill wet grass didn't want to tear up the grass, and it worked fine until I tried to back up grind grind grind! Worked fine in low and 2 wheel. I have never liked electric shift or auto hubs, give me ***** and levers any day. Could this be that the shift was incomplete? Idiot light said 4x4 high and I tried shifting a couple of times. Seems strange to me that it backs up fine in 2 wheel and low but not 4x4 high, does it run on a different shaft or gears in 4 wheel drive? Any one seen this? Please help educate me. Any insight would be much appreciated. Thanks for looking

 

 

At one time it was a very common practice to back up a few feet to fully disengage from 4lo into either 2Hi or 4Hi. I haven't experienced that quirkiness on my 2011 truck.

 

Thanks for replies, I will wait and see if I continue to have problems, then decide what to do.
