Had the dealership monitored the torque converter (TC) lock up behaviour with their scan tool?
I had symptoms that were VERY similar, unless I'm mis-understanding something in the OP. Mine ended up being the TC and haven't had an issue since it was replaced.
Yes! When mine is given the command to lock, it starts the stutter. Had the driveline tech for a ride along and whenever he gave it the command, the stutter would start. I agree that it's likely the converter, but they aren't willing to replace it. It could technically be something motor related that is instigated by putting the motor under load when the converter locks.
He also noted a misfire during those events, but is that the motor misfiring or is the faulty converter causing it with a fast lock/unlock/lock/unlock? Car had fresh plugs, a cleaned out CAC, and was low miles at the time.
Now nearing 50,000 miles and the car runs no better or worse. When the wife drives it, she just drives in sport mode and beats the snot out of it. Running it hard avoids the stutter.
