Throughout, I felt nothing that would indicate that the transmission was trying to find the right gear. In fact I didn't feel a shift at all, and imperceptible shifts are not a hallmark of these transmissions at those low speeds.
I suspect the lag is at least partially a function of the drive by wire throttle programming. I'd like to datalog the position of the accelerator pedal versus the position of the throttle valves under these circumstances - past experience doing so (on other makes) has always proven interesting.
I posted this in another thread too.
"The car does not down shift from 3 to 2 fast enough and rolling through a corner and then gassing it will show the problem. Easy solution I discovered on the track, manually downshift to 2 going into the turn with the left paddle (you do not have to be in manual mode to do this either). Boom, no lag out of the turn. You just have to remember to do this if you want the quick response. Careful though, you will burn through tires with all that juice coming out of the turns. "
