My 2015 Fit auto transmission suddenly began making loud knocking noises, sounds like right at the top of the ending. Dealer says he hasn't seen this issue before on a car with approx. 12K miles. They need to remove the valve cover to start diagnosing - has anyone on the forum heard of this type of problem? At least it's under warranty. . .Love my Fit - runs great, good gas mileage, etc. But this is odd. . . Thanks!
