Throttle response is not smooth and is most pronounced before engine is at normal operating temperature. Depressing the accelerator results in an initial response but then weakens noticeably almost as if the traction control has engaged.
The 1-2 shift (and sometimes 2-3 shift) "rings" like a wound up spring uncoiling. The sensation is similar to the torque converter engaging and disengaging several time.
On hard acceleration everything is fine. The computer driven drive train has no problem deciding what it should do when told to accelerate with abandon, but when accelerating with some moderation, it seems to have a hard time making up its mind.
