Official Nissan 370Z Synchro Rev Match Transmission thread

Okay, after getting pms from many YouTube users wanting to know about How the new 370Z "SynchroRev Match Transmission" works, I have decided to upload this video.

Quote:

From Nissan USA website

Groundbreaking SynchroRev Match manual transmission technology, available on the Sport Package, monitors the 6-speeds clutch pedal operation, shift lever movement and vehicle speed. Shifting to a lower gear automatically blips the throttle to the ideal engine RPM for a smooth downshift. With smoother shifts helping to keep the chassis balanced, this transmission is able to deliver handling and power.

WHEN DOWNSHIFTING
-The engine speed is automatically increased to the target engine speed before the clutch is engaged.

WHEN UPSHIFTING
-The engine speed is automatically kept during and after the engine speed lowers to the target engine speed.

DEACTIVATING THE S-MODE SYSTEM
-To deactivate, push and hold the S-MODE switch for
more than 1 second. The S-MODE indicator will
turn off.

-To reactivate, Push the S-MODE switch .The S-MODE indicator on the instrument cluster will show S.

Okay.. Now, I was NOT aware of the up shifting system until today :confused: . So does this mean, when I upshift, I just have to clutch in and shift the gearbox without worrying about the gas padel?

There's an upshift??

So does that mean I can finally double-clutch like I should, instead of granny shifting??

So when the car is started....is synchro rev match automatically always on?

No. You have to activate the S mode. BUT once activated, it'll remember the setting. So, next time you start the car up, it'll be on.

Interesting. Thanks for the info! :tup:

Wow, I think that must be true, and would explain what I experienced during my test drive yesterday. I was having a hard time upshifting the car when I was driving it, but I thought it was because I wasn't used to the 370's tranny and clutch. I distinctly remember on a couple of occasions the engine revving slightly when upshifting, even though I hadn't touched the gas pedal.

I have driven the 370Z myself and, even before the test drive, I was curious to see if the syncro rev-match feature did anything during upshifts- it did not. You can easily jolt the car with crappy shifts (not rev-matching your upshifts). Maybe im missing something here, but atleast during my test drive, it didn't do anything for my upshifts.

I see that as a good thing. Rev matching itself is a peace of cake during downshifts. Now if someone really needs to get their upshifts rev-matched or is just to lazy to do so themslves, then that's pretty sad. Even with the optional off-button, that person should look into a 7AT instead.

*chuckles*

Am I the only one that got that?

I did not know there was anything for upshifting. We need some more info!

Nope...LOL I need NOS haha.

I noticed this in a video a few weeks ago. I didn't know it was the synchroshift at the time, thought it was just a heavy flywheel, a clutch delay valve or something of that nature.

You can actually hear the upshifts hang on this video of the Mine's track test.

After this thread, I really don't think so anymore.

Okay guys, I got the official answer. Big thanks goes out to the member here (who's really high up in Nissan USA) who developed this technology for the new 370Z.

For drivers who take longer to shift, this can help them be smoother since the revs won't drop down to idle immediately.

Of course, if you wait too long I believe the revs will go to idle, but as soon as the gear shift lever is moved in the direction of a gear the system will set the revs at the appropriate RPM for that gear.

Sorry for the lengthy explanation...it's much easier to understand if you have a chance to experience it.

You learn something new everyday! :tup:

great to know :icon17:
