By the way, you can also show the dealer that when revving the car in P, the throttle response is instantenous (again, I can point you to that thread if you'd like) - verify this first. Only when in D, does the tranny not engage fast enough... I've experimented with this a lot. It's not a throttle issue at all. Has to do with the tranny big time.
Basically the tranny engages late and hard, rather than early and with some slippage for smooth, yet decisive take off.
