I've had my '00 Limited (V6 auto, 4wd, factory e-locker) for just a few weeks now. It has 175k miles and I've only put 800 on it. Today I noticed a fairly loud (but not too loud) metallic sound coming from what seems to be the transmission. I have very little knowledge on this subject and am looking for any help I can get. It happens whenever I'm on the gas while in gear. Happens in every gear including reverse but not while in park/neutral. It sounds like something is spinning and has come loose; two metal parts rubbing against each other. I'll try to answer any other questions you could have. Any help would be appreciated.
