The force of the wreck broke the foot of the adapter between the TH400 tranny and Quadratrac transfer case. With mushy motor mounts up front, I had to replace this piece since the drivetrain kind of wandered around under the body when wheeling. It's a good thing too, as the Pepto Bismol-looking stuff on the bearing is ATF and water whipped to a froth. Needless to say, I had to change the fluid and filter rather than have problems down the road, or trail. Oh yeah, I had a spare adapter that needed the threads fixed, so that part was free. But it cost a Corona or two to have my buddy help me bench-press the case back into the Jeep while laying in the mud. Total cost: Six-pack of Corona, 5 quarts of ATF, and a transmission filter -- $39.47.
