Need some Insight, I have an 06 f350 6.0 lariat fx4 with electric shift 4x4 was headed down the road going about 50 and went to give it a little fuel and I heard a loud pop, and the power loss to the rear wheel was instantly gone. No grinding or whinning gear noise. Now that I towed it to the house I started it and put it in drive and you can hear a consistent click/tick in any gear. The truck tries to pull and you can feel it move ever so slightly. I checked the fluid and there is no color change but it smells like a burnt clutch, anyone have any ideas on what the issue may be?
