It's an excellent piece of kit, it really is. Left in auto it'll get to 7th quick as, and return great MPG. Pop it into Sport auto (where I tend to leave it) and it's absolutely perfect, never caught out on gear and adapts all the time if you're pressing on or pootling. Sport Plus is just mental for the road and best left for the track, however Sport Plus and manual mode gives lightning-fast changes with the little thump in the back at WOT, and is how I drive the car when on a blat.
It can be a bit clunky on the very first 1-2 shift on a cold morning, but then the oil is stone cold so to be expected. Other than that, it's flawless. It's even quicker on the 9x1 cars.
