The new DSG gearboxes from Audi will rev match on the downshift...but they are true automatic manuals. Not just automatics with a manual option and aggressive shift points.

Ok so what about all of us who haven't been rev-matching? I have 5k miles on my coupe and I've been downshifting by gradually letting out the clutch, has this been killing my clutch and syncros? Also I've occasionally tried rev-matching but more often then not I've reved a bit to much, and when I let the clutch out the jerking motion is more notable then it is when I don't rev-match...I guess I'll be trying what MRMCDERM suggested from now on...But honestly, how much damage have I done? I've been very careful, I just haven't been rev-matching...Thanks guys

since u only have 5k on ur car, u cant have done much damage, unless ur grining gears also. but try to practice rev-matching. one thing that helped me was trying to remember what speeds match what rpm. after a while it becomes 2nd nature

im dont think u can rev-match in an auto, but i think that downshifting in an auto will wear down ur trannie in the long run

Escobar929- Thanks for info and the advice...I'll practice it and try to remember speeds with rpm's and gears...I haven't been grinding during my downshifting...I just press in the clutch, downshift, then slowly let the clutch out until it catches...One more question for ya, do you guys use this method of downshifting for slowing down and stopping? Or do you only use it when downshifting to get the rpms in the best possible powerband, right before you smash down on the pedal and take flight on the freeway? Thanks

And don't worry so much about trying to watch RPM's. I actually don't. Practice enough and it will become instinctive. I actually listen to the motor. My prior cars all had eshaust systems so it was a bit easier to hear, but luckily the G35C is loud enough to hear. Though it did some getting used to the much lower noise level. In some cases, I actually have to even feel the frequency of the motor if there is too much ambient noise. I'd say it's probably imporoved my abilities slightly.

i think for auto....downshifting is fine if you are trying to accelerate..(say you are in 4th gear going 30mph..and you wanna speed up quickly...you can downshift to 3rd and stump on gas)...but from what i read on the forum...downshifting for braking in a auto car can increase transmission wear on the car (not confirmed by infiniti mechanics...wish someone did though)

oops...I thought you were talking about a 6MT
Heck yeah its ok for you to downshift. It doesn't cause any additional *noticable* wear on the engine (though people will argue that you'll only get 150k instead of 200k out of the motor).
The torque converter is going to absorb a lot of that transition energy...and over time the heat build up may cause the ATF to break down faster. Just adopt a more aggressive replacement schedule

Yes you can. The TC has enough slop enabling you to blip the
throttle before the lower gear engages. I do it all the time
when driving AT cars. The G35sedan that the dealer loaned
me was a 5AT and it blipped no problem while downshifting.
It goes like this:
You're in 4th, let's say. Downshift lever to 3rd, blip gas.
the tranny will downshift smoothly to the lower gear.
The 05's come with auto-rev matching (blip throttle) on the
AT's. very cool.
