also SRM on MT isn't all that smooth at lower rpm with light braking. it is only smooth on moderate to aggressive braking/downshifts. so i tap the throttle to help rev match during light braking/downshift. might be the same on AT's.
I'd of suggested the same. Maybe only on sport package does SRM?

Hey maybe it's time for an auto vs manual thread.

The 7AT has a strong downshift especially in the lower gears. I rather like it because that's how it's supposed to feel. This is not a luxury car for smooth shifting. If you shift a G37 7AT it feels weak as sh1t

This is probably the OP's problem. 4th to 3rd isn't much of an issue, depending on what RPM you do the downshift at. 3rd to 2nd - well, let's just say you better not be going very fast or you'll feel it (and it probably isn't very good for the transmission either).

Yea I just got back from driving it again and its definitely most prevalent in 3rd to 2nd, but noticeable in 4th to 3rd. Is there any downside to letting the cpu downshift for me? I suppose I could just do that, but figured it'd be better to downshift myself *shrugs*
