I plan on taking it to the dealership soon to record it formally. I drove a manual I30 and it drove like a dream. The 6 speed trans is a very beefy unit. Many owners report the same sticky clutch problem at various speeds. But this is not the only problem I am having, the new engine seems to be a lot louder and a bit sluggish too. I have never liked the way the G35 clutch works.
This results in the clutch not coming up from the floor all the way. I was told to go easy for the initial 12-15k. They also told me it was my clutch, but i knew better. The only problem with it is since the gears,hubs,etc are so beefy they are also heavy. Hydraulic clutch fluid boils and contaminates similar to gm problem. A few months ago I started to have intermittent problems going from 1st to 2nd.
All my gears are fine but when I drive fast I go good through every gear except 4th. If the aftermarket flywheel reacts better than the factory then maybe I shoud recommend aftermarket to solve some problems. The clutch uses dot3 brake fluid which is being contaminated and turning brown resulting in clutch problem. I took it to the dealer for an oil change and had them check the problem, they found nothing wrong! I have 60k miles on it. The fluid is somehow being overheated. The dealership received an approval to replace the engine, and at 14,500mi, after just about 6 months, I drove out with a new one 10102-ac7m9. Infiniti claims this requires a new clutch--given that the owners have had their problems at various points of mileage, I am not convinced this is related to the clutch itself.
Finally the last one said it was the tranny synchros is my theory and fixed it for free under warranty. But, just in case, I had them change the transmission fluid. That's why the ealier ones failed more often. The dealership addressed the problem at 50,000 miles, but it has since returned. When I drive normal I go through 4th gear easily.
I was under the inpression that the dual mass flywheel was necessary to counteract engine vibration or vibration during engagement. What should I do I would like to know how the clutch feels and drives. I've searched a lot on the internet seems to be a common problem and as of right now inifiniti claims no knowledge allegedly. After driving about 1000mi now, I am running low on oil. If not you won't throw 5th all the way and the 5th syncro won't last long.
Definitely not the ride I got used too!!. I have a 2004 G35 Coupe with a manual transmission and about 49,000 miles. . I just checked it myself. They also put in a new clutch and flywheel free of labor charge i just bought a 2004 a few weeks ago and i too just got back from getting a free flywheel and clutch. The later transmissions I think 05 and newer they changed the syncros from a 2 piece to a 3 piece syncro. For me, it's happening at any speed whether it is slow or fast.
I took it to 2 dealerships and they couldn't find anything. I could never understand why they did this to the G35. I was called in 4 more times after that every 1,000mi specifically for oil-level testing. The job of the syncros is to speed up or slow down trans components so they will mesh easier. Now, about 3,000 miles later, the problem has gotten worse; about every 3rd shift from 1st to 2nd. There are many G35-devoted websites and blogs where G35 owners complain about the same problem, but it does not appear they have followed up by filing a complaint. It seems replacing the fluid and using dot4 might render a fix.
The first time I did this I redlined because my 4th gear is messed up. . . . .
