I love SRM. It was the deciding factor on purchasing the Z with the 6MT. Other than it's gorgeous, felt like race car getting into it (to me anyway) and had more go than anything I had driven in the last 30 years.

But if it had not been for SRM, I probably would have bought an auto.

The auto has SRM if you have it manual Paddle mode.Revs matches just like a stick.

Doesn't every AT? My wife's Acura has paddle shifters. If you downshift, it rev matches.

Not familiar with other makes with paddle shifters so u may be right,but other late model automatics without paddle shifters,that I have driven, do not rev match.I was just saying that our Nissan auto does rev match for those using the excuse they bought a manual instead of the 7AT ,because of the rev match.And also our auto rev matches when using the console stick ,so you do not need paddle shifters necessarily to have auto rev match.Which brings me to ask of those who own a Z with a 7AT,but without the paddle shifters,do you get rev match feature when downshifting with the stick in manual mode.

It is the exact same rev match with the stick in manual mode as well as the paddles.

rev match works on both paddles and console shifts.

the no paddles thing on the base 7at is new for the fucked new options nonsense Nissan went with sooooo I wouldn't know lol need a 2015 owner to chime in on that one.

Are you saying that an AT without paddle shifters does not match engine and transmission speeds when downshifting? I don't believe that is true. All AT cars rev match or else they would just grind the transmission whenever they downshifted.

I don't know of any AT car with paddle shifters that does not rev match. In an AT car without paddle shifters you might still have a stick mode similar to the Z's manual mode - and the car will rev match whenever you use the stick to downshift. Or in an AT car without any sort of manual mode, you just mash down the gas pedal to downshift. The engine RPMs increase when the transmission makes the shift - aka rev matching.

Yes that's what I am saying.My 2015 Toyota Matrix with a 4 speed auto does not rev match.All rev match on a auto is ,the ecu brings the rpm up before the clutches or bands (or however the particular tranny engages)engages the next gear down.On a normal auto the clutch or bands engage the lower gear with some inherent slippage and as they firmly lock together the RPM climbs to what ever speed you are doing,not before hand like a rev match.All my Trans Ams with Turbo 400,s never rev matched.As a matter of fact, I actually destroyed a case on a Turbo 400 tranny downshifting into second before I had slowed down enough years ago.Hence my forum name TA-Kid,mind u I am not a kid anymore or own any Trans Ams anymore either.

AT rev-matching is a feature of computer-controlled transmissions - not available back in the Good Old Days. I'm rather surprised that there are newer ATs (eg, your Toyota) without rev-match - once you have the algorithm, adapting to different transmissions should be almost no-cost to the manufacturer. Maybe it's the cost of the sensors on the stick.

I'm sure glad mine works. I've hit the down shift paddle by mistake several times, while driving "spiritedly " !

My Dodge Charger auto did not rev match either.Corvette has it now and a lot of imports do,but the domestic Auto,s are late to the party.

not true. all auto's do not rev match. for example, my buddy's lexus is auto and if i move the shifter into a lower gear, yes the rpm will raise, but not in the rev-match way. it sounds like a manual downshifting where you put in a lower gear and slowly release the clutch where the rpms go up on its own and no gas pedal involvement for rev-matching whatsoever.

So non-rev-matching AT transmissions just slow the speed of the engagement so as not to shock the drivetrain yet no revs to the engine are used to bring up the RPMS? Interesting. Sounds like someone driving a MT that doesn't know how

go drive an auto other than a 370Z, and move the shifter to a lower gear while driving, and you'll know what im talking about.

and the last comment, not sure if you are referring to me, but the 370Z is my first auto tranny, and have been driving manual ever since i got my license.
