I was wondering if anyone else has experienced, when you come to a stop and let off your brakes, but before you step on the pedal, you sometimes feel a slight jump, or bump, or ?. Mine does it ever once in a while., but only from a stop, before you accelerate.

Yes, this happens to me. I believe that this was explained in an earlier post as a symptom of a torque converter design flaw, but not as a sign of impending failure.

It was GMCTD

"Vis-a-vis the transmission, that clunk or bump you feel at start-off is Chryslers typical torque convertor problem - to prevent excessive heat build-up when the vehicle is stopped and the trans is in any selected gear range, the t\c is not charged at idle, which causes a slight delay between pedal and go as the pump fills the t\c with fluid and the vehicle begins moving - that's the 'bump' you feel - some are worse than others

This is (im)perfectly normal - most any shift kit (I prefer Transgo) will cure this problem and most of the slush-shifting - the slush-shift is mechanical, not electrical: the orifices and springs in the valve-body control the duration, or 'ooze into', of each shift - the ECM shares control of the interval between shifts, the TCM controls the event: 1-2-3-4-5 - you'll need an aftermarket torque convertor (you know the one) to cure the rest of the slush-itis "

Mine got worse and worse, turned out to be a loose motor mount.

I think others here had loose motor mounts also with same problem as yours. I would check that first if I was you.
