I have an '04 Grand Cherokee with a 4.0L and about 42,000 miles. The problem is a loud vibrating / humming sound when the transmission is in neutral or reverse. No sound in any other gear. I slid under the Jeep and the vibrating noise is loudest from the transmission pan. Sound has no effect on it reversing.
I changed the fluid and filter, but this did not help. Any ideas?
