The transmission does seem to shift faster from videos in the facebook groups

Being the G(Z) TCM is used and that's what dictates shift speed, are you sure the Q transmission (hardware) is doing the faster shifting or is there a tune involved feeding higher load commands to the TCM and making the Q trans shift faster?

My 7AT shifts pretty dang fast with the TCM getting higher load % via the ECUTek tune.

What's the FB profile name?

Look up Adel Taw in the "VQ35HR / VQ37VHR Discussion" group on FB. He's the 1st one I believe that did this swap on a G and has a few videos. His G is supercharged so there most likely is a tune involved making it shift faster.

Also, so far I haven't seen anyone attempt this swap on a 370z.

I think he did the video linked in my original post.

He swapped the solenoids from the G transmission to the Q transmission as well, i believe.

I agree that the shifting may also be adjusted with a tune, but I've also heard that the Q's transmission will hold more power.
