So we were out all day, no issues. We came back to the dock and then this grinding started. Its a 2000 Moomba Outback. Transmission fluid is nice and red, does not smell burnt, and checked and saw no metal shavings in the fluid.. Anyone have any ideas? Best part of the video is my wife saying "Thats not good"
