I burnt the fluid really bad on a trail trip. I thought I did some severe damage. I put in 3qts. ATF and 2 qts. power steering fluid. That's all I could scrounge from everyone. The fresh fluid was all my C4 needed. That was 10 miles in on the Dusi/Ershim trail. I serviced it when I got back home, it' been fine ever since.
