Right now I'm in the opinion that if it's going to be a problem, I'm going to get them to do as much as they can. I appreciate your suggestion, and come time my warranty is up (if I still have this car), I'll probably end up taking your suggestion.

In any case,
Thanks

What being done to the 6mt? At this point I would be hesitant to consider another G due to my 2 tranny replacements at 40K and again at 50K. Not too mention less that smooth driveability due to the clutch setup. I've had my car since day 1 for over 3 years and still have trouble getting a smooth start and transition to 2nd.

For all who need clarity with shifting....

Check out this site, very useful and accompanied with pics you can get an idea for what is called "heel toe downshift" not the same as "double clutching"

Although its referred to as a racing technique I'm sure the more experienced drivers out there will see just how important it can be to relieve undue stress on the manual tranny.

double clutch can be used for upshift and downshift. heel/toe is used only for downshift.

Double clutching, can be done in a car with or without synchros --> Clutch in, move shifter to neutral, clutch-out, match revs to desired level based on lower gear your going to go into, clutch-in, move to desired lower gear, clutch out. (2 clutch ins, hence the doble clutch)

While doing this in cars with synchros isn't necessary, as has been stated, it can also be used when wanting to downshift while in bad driving conditions (slippery roads). By double clutching it makes the transition smooth, as opposed to being relativly jerky by letting the synchros handle the rev match.
If you correctly match revs when downshifting, there's no difference between this and double-clutching regarding changes in drag to the wheels (hence the concern about conditions). Believe me, you learn to rev match correctly when you ride a motoercycle in the rain.

As stated, rev-matching is a good thing, double-clutching is not necessary (if it's fun for someone, go right ahead )

G35NOW!: I wouldn't say double clutching is necessary in transmissions nowadays, however with my car, when the transmission is cold, it is. Quality transmissions don't require it at any time, however this transmission is the G's, if not Infiniti's achilles heal (sp?). Keep it in a truck where it should be and give me something that belongs in this car.

With said, have a good day everybody!

ok so how exactly do u 'rev-match'? does blipping the throttle mean u hold the throttle down just a little bit to keep the revs higher, or do u just tap and release to get the revs up quickly??

  • Push in clutch and begin moving gear lever
  • Tap the gas pedal (push it down a bit to rev the engine - with practice you'll know how much - then let off quickly)
  • Finish gear change, let out clutch smoothly before engine revs come back down. If you do it right, you'll be in the right rev range for the new gear at the same speed. This way drag on the rear wheels is smoothly changed vs. abruptly
Note that this all happens quickly vs. deliberately, it should not change your speed of shifting.

And this from an AT guy!

I kept on reading this thread waiting for someone to finally reference heal-toe.

like some others said, heal-toe=good, and if you ever want to go to a DE you will be ahead of the curve. Heal toe is really an art!

No need to double clutch unless you are driving a 3 on the TREEE!!!!
