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

You can't turn off the DRM right? It's always automatically supposed to work?

Right, no way to disable it. It's part of the 7AT, regardless of package. A lot of AT's actually have some form of SRM.

i downshift at the lowest rpm possible and its not jerky. A lot of times if you dont downshift the computer will do it for you and its very smooth

but us MT guys have smooth shifting while you guys are hiccuping at lower speeds? is that ok?

Here's an idea... keep it in D. It won't jolt. Lol. Manual is for sport shifting not smooth shifting... but I do have one question...
Are you shifting from the paddles or from the sttick? The paddles shift way smoother than the stick. Keep the rpm"s below 3000 when downshifting and use the paddles. The Z is not completely smooth when downshifting even at its smoothest point in manual mode.

Don't even down shift in manual mode... just slow down and let the car downshift for you. That is the smoothest way. If you manually down shift it will jolt.

It is a transmission that wants you to have fun. This is how it was designed.

is that the same philosophy they used for the steering lock?

Slightly different, the steering lock is for the Z to have fun while Screwing-Lock the driver.

If you wait too long to downshift from 4th to 3rd, the computer will downshift for you at the same time you are downshifting, then you end up in 2nd with a high rpm and jolty. This has happened to me on several occasions.
