I can also confirm the fix, Basil.
I had the software update mentioned in Service Bulletin LS307-003 and LTB00101 applied to my '06 RRS in April. The transmission pause then corresponding shunt is completely gone.
There is still a very slight hesitation in remaining in the system due to the inherent nature of fly-by-wire throttle control. But you wouldn't notice it unless you were looking for it.
