Automobile magazine reports poor clutch operation
Here is a comment in the July 2008 issue of Automobile magazine concerning a long term driving test of the Infiniti G37:
6259 Miles: Staffers still don’t have a cozy relationship with the G37’s pedals. “The clutch grabs too high, and the throttle is too touchy, making smooth shifts difficult,” pens Noordeloos.
Unfortunately, that is my experience with the Z as well. Smooth transitions when up-shifting or starting from a standstill seems to require running-up the RPM’s and slipping the clutch more than what I would like.
Something else… When shifting, the RPM’s remain high way too long after powering-off the accelerator pedal. This is very annoying in a car meant to provide optimum performance. My car is “stock.”
Anyone else notice these deficiencies?

very common complaints about these trannys.
look into the dwolf mod to help with the high engagement point. for me, it was a huge improvement.
for the rpms not dropping fast enough...maybe look into a lightened flywheel. i believe the inertia of the stock dual mass flywheel is keeping the rpms from dropping. tradeoff would be that starting from a stop may be a bit harder and some "cement mixer" noise. but the rpms should rise/fall much quicker. this is only from what i've read about lightened flywheels. i don't have first hand experience with one but plan on it in the future.

I've been given a stock g35 and stock g37 (both 6 m/t) for loaners. The g37 clutch action felt worse than the g35. Much higher engagement and for a stock setup it was really firm than totally loose up top. Hard to explain. I was very happy to be bak in my g with aftermarke clutch/flywheel and dwolf kit. I usually prefer a/t loaners from the dealer now, go figure...

^^ Interesting… That your assessment is that the G37’s drivetrain characteristics are quite different from the G35. Actually that seems to be the opinion of other testers/drivers.
