you might re-read the manual and on my door and other vehicles with OD all say "Do not tow in overdrive" this adds strain to an already weak transmission. i agree with the above as well does it do it if in drive? or in any other gear if you manually shift it? what happens if you put a few hundred pounds in the back without a trailer same thing? you checked the u-joints and slip joints?...mike
