I am not a Transmission Tech but if memory serves me correctly, we repaired a string of GM vehicles where the solenoid that controls the lock up of the torque converter does not release and would give the symptoms you described. Sediment collects in the solenoid preventing the release of the pressure that locks up the converter. It would give the same feeling of driving a manual transmission and coming to a stop without pushing in the clutch.
