DB9 software update anyone heard of this for shudder
Saw this on PH and I've had this problem. I replaced coils, plugs and injectors and still have it.
Drivetrain software updates done (2005 DB9: Symptom: With 'Drive' engaged, foot on brake and car stopped (like while stuck in traffic) there is a periodic and fairly frequent shudder that I feel, much like a rough idle. But there's also a bit of noise that accompanies it that seems to come from somewhere below the car, possibly in the area of the torque tube or driveshaft. Shifting to 'Neutral' alleviates the problem leading me to believe it's not an engine misfire or idle problem. I believe the symptoms are the same while stopped with 'Reverse' engaged.)

Clutch learn
Search clutch learn procedure if you've never done this. I'm assuming you have a paddle shift car.

OP has a DB9 with a ZF 6-speed auto. Yes it has paddles but it's not related to what you think as far as a clutch learn.

Get a good code reader, first time I had a shutter I did the misfire correction and the shutter was gone.
