Fair enough, Have you opened up the pan and case to see how much sludge got into it. I would start with that, clean everything as best you can. Start with new filters and fluids. Pull the rear diff cover as well. A buddy of mine does mud bogs, However, first time out he didn't have everything sealed up the way he should have and the trans/case/trans cooler/rear diff was full of mud/water after they pulled him out after his first run.

How does sludge get into a transmission, transfer case and differential. Water maybe but mud? My guess is a transfer case issue.

I believe you burned up a already new death clutch.

Automatic, mud was dry not like soupy. Appreciate the help.

The 4R70/AODE trans is known for having a very weak Direct drum and bearing assembly. The back and forth rocking could easily have broken the bearing. Causing the direct drum to move around between the ring gear and planet assembly. This will starve the Direct clutches and cause the trans to whine and not have any gears.
