Intermittant un-lock of torque converter

When running my 99 Dakota on the hiway at 70ish mph and the cruise control the
lock-up torque convertor will un-lock for a fraction of a second every once in
awhile. It only seemed to happen when the cruise was on and I figured it was
one of those things that was on the ragged edge and the computer didn't know
what to do.

Well over the week end there was some traffic on the hiway so I wasn't using
the cruise and noticed that if I hit a good bump in the road (expansion joint
or the like) it would drop out then too.

It's only for a fraction of a second and the rpm will jump maybe a 150rpm
before it locks back up.

Besides looking for a loose connection anyone have any hits on what it might
be? There are no codes and the tranny shifts fine otherwise and is full of
ATF+4.

Thanks,

Dave Clement
