I just switched to Red line and I didn't notice a difference until a few days after it became smoother but notchy sometimes specially when it's cold.

Another problem I'm having is a whine in first gear my friend said he doesn't have this in his Nismo, any thoughts?

Air in the clutch line would prevent the CSC from being fully engaged, otherwise the only other thing I can think of is that something is out of adjustment preventing the clutch master from having the correct range of travel.

Nearly 3 years of racing on my car on the stock clutch and I don't have anything like this issue.

My clutch and transmission work just fine - 3K.

Whine in first, only in first? does it sound like its spinning up? All the time in first or only when you accelerate?

Which is why I'm starting to think its something stupid, some adjustment is off somewhere...

Over 25k miles and I do not have this issue.

Dembflyr · 09-06-2011, 11:37 AM

Is there anyone who does have this issue that hasn't had their transmission removed?

My car had the trans replaced under warranty so it's possible that the dealer didnt bleed the clutch properly.

In high RPM doesn't go until a shift or slow down I wanted to take it to the dealer but didn't have time. And I feel like there is air in the clutch it has like few inches until it starts disengaging

After getting the DXD Stage 4 and ZSpeed CSC, all of my gears are notchy and take more effort to get into gear. Sometimes it's smooth like stock. There are times I couldn't get out of 1st gear after parking the car. Is it true that realigning the shift gates can alleviate this issue?

SeeyaBud86 · 09-07-2011, 10:34 AM

Ever since I bought my Z I've had a whine when accelerating in all gears. In fact, when my car was stock, on the freeway it was so audible cruising at higher rpm that I had to put my music up high. I don't have the "lurch" into first, but it definitely does not like going into first gear on a downshift (15mph and below).

I also have noticed that my car has a problem with shifting into second from first gear when redlining. NewYorkJon34 lives near me in Naples, and he has the same problem too. We have concluded that we have to give the car a second to settle itself, with the clutch engaged, to get it to shift into second. I have also noticed that trying to shift too fast makes the gear grind, it's not that I am shifting improperly but sometimes I have to almost granny shift it. This problem seems to get better, not fixed, with SyncroRev off. At first, I thought maybe I was just bad at shifting in general, but my father recently bought a Z06 which I can shift perfectly at redline in all gears (don't tell him that =p). So the only thing it must be is the tranny in our car.

I have the same clutch/csc and the same issues, 1st gear can sometimes be extremely difficult to get into, other times its like stock. Do you happen to know what transmission oil you are using?

our synchros kind of suck, I usually pause from 1st to 2nd as well. Trying to shift as fast as id like usually results in a loud grind and me looking like I can't drive.

Do your problems happen while Sync Rev is on or off, or both?

Mostly when it is on but it still happens sometimes while its off. I've noticed that shifting a little lower than redline helps make it a little easier. Around 7k. But this whine noise is always there and always has been. I just haven't bothered taking it to the dealer for it because other people have and Nissan just says its "normal." I've decided not to waste my time with them. After I got my exhaust I tried to forget about it, as my exhaust is louder under acceleration. I thought maybe a lighter flywheel would help the problem, but RCZ had one and obviously it didn't help. I'm just sick and tired of the way the clutch/gearbox/tranny feels on these cars. It's made me think about a new STI a lot.

I have the EXACT same issues. Annoying whining noise when cruising on the highway under acceleration, and of course the 1st to 2nd grind when trying to shift fast at high RPM.

While I dont agree that our transmissions are horse $hit, they are definitely not very refined. On top of the problems mentioned above I find it rattles and chatters all the time.

Yea I've noticed that driving with Syncro and VDC off helps a little bit. In my opinion I think the problem is with Syncro. I think it makes the tranny "think" too much. I don't know how to explain it.
