I think it is pretty common with that gearbox. My X350 used to do it and I was disappointed when I bought my '07 XKR to find out that it had the same gearbox and same issue. When the engine was cold the jerk could be quite violent.
Clearing the TCM adaptations used to get rid of it for a bit but it would come back eventually. Driving style probably makes a difference as 95% of my driving was around town but the gearbox seemed to perform better after a longer drive.
My 5 litre XKR is OK as that has the later gearbox but my Aston Martin Virage has the same gearbox as the 4.2 and does it occasionally.
