Im new to the diesel world and this is my first post but any help would be greatly appreciated.

I got my 2004 F350 6.0L King Ranch stuck in the mud and finally had to call a tow service to winch me out. When he was pulling me out I had the truck in 4 wheel drive and getting no power to either axle. I put it in two wheel and after a few moments the rear wheels started to spin. When u was finally out I could tell there was something wrong because I had to give it alot of throttle to move the wheels. I decided to get it home and clean it up and check things out but about 2 miles down the road I lost all power to the wheels and the engine just revved but no power at the wheels. I got under the truck and had someone get in the truck and put it in drive and reverse but the drive shaft wasn't turning. I pulled the transfer case and put it in drive and the shaft from the rear of the transmission that goes in the transfer case spins. I am hoping this means I have a bad transfer case and not transmission but before I spend the money on a transfer case I want to ensure this is the problem and not something else such as electrical. Any suggestions or know how on how to determine the solution would be great.

It'll sound weird.... but check the connecters on the FICM...there are three long plugs... if ,I believe the rear plug is loose...the motor will run.... go into gear, but there won't be any throttle response... good luck

If the t-case is out of the vehicle spin the input and see if the output spins. Try it with some resistance from your other hand too to make sure it isn't just oil roping causing the output to spin. If it spins in 2WD try it in 4WD and 4WD low range. In 4WD use the same test for the front output. If it spins in all ranges the t-case is good. If not something in its broken.
