I tried to look up this TSB on a google search. I think i know what your talking about. I had a 96 that made a buzzing sound when cold the first time you would back up in the morning. An oil and filter change solved that. This is much louder and more metal to metal sounding. What all is moving when your stopped and the trans is in drive? Is the pump turning all the time? The outside of the torque converter is turning but not the inside correct? And is that call stalling? Like stall speed?
