Well I got the excursion stuck. I put put her in 4 low, it went forward, then when I went into reverse she didn't move. The rear driveline is still attached, I can't see the front. Whatcha think guys? Tranny?

 

Did you shift to 4low correctly? ie. in neutral while all 4 wheels are stopped with the brake pedal depressed? When you say stuck do you mean stuck in the mud? Do you hear anything when you put it in reverse, like grinding? What happens if you put it back in a forward gear? Did you try going to park then to a gear again? Need more details.

 

I was stuck in snow. Yes, when I shifted in to 4 low I brakedand shifted from neutral. There were no abnormal sounds the 4X4 light went off and then no power to the wheels. When I tried to put it back into park it made angry noises.
