Tonight there was a huge storm, and part of the interstate on my commute had partially flooded. Only about 3 inches of water was there, but I drove through it. About 5 minutes later I noticed my clutch was slipping, even in 1st and 2nd gear. The transmission also made a horrible chattering noise whenever I would release the clutch to start driving. I was fortunately able to limp home. The clutch was replaced only about 8000 miles ago, and the flywheel was replaced about 75000 miles ago. Is my clutch just wet and needs to dry off, or is it completely shot. Or perhaps my flywheel is warped. Any help on this would be greatly appreciated.
