Ok I know some of this has been posted before (so please don't flame me). All i want is some advice and input for what I am experiencing.

First off, today I noticed after ragging on my car a little bit I noticed a slight "whinning noise coming from the transmission. I was like great . I didn't skip gears or grind. Just some fast heavy shifting as well as downshifting, I always rev-match btw. I let it cool down a little bit then took her out again and it sounded ok for about 25 min, then it started again, but alot lighter than before. It sounds like a supercharger as I rev through the gears. I'm picky so i notice it, but it really isn't that loud...yet. Is this going to get worse?

Also I notice on this tranny that unless you have the rpm's just right for shifting and if you let off the clutch a little too fast the car seems to have a freakin spazm. It's the most unforgiving tranny I've ever driven, and I've driven my fair share. I have gotten use to it as I have 2500 miles on the car, but still I wish it was smoother. I am also noticing that when switching into my 3rd gear it is harder than the other 5. It's not grinding, more like I have to almost jam it in there, could this have something to do with the whinning.

My clutch chatter has also gotten louder little by little, is this normal? And one last thing, I notice when I turn off my car with the clutch pressed in it turns off alot smoother than with the clutch let out. Why is that? Now I always have it in when turning it off.

Thanks for any input guys, and sorry for the short book LoL, I just wanted to give you all the details.

 

Nobody has any ideas?

 

my third gear is like that too, feels like the gears are grinding when i shift into it. it was never like that when i got the car new, now i feel it more, especially when i am shifting fast.

 

My car had this same problem and so has others...for me, infiniti replaced my tranny and throwout bearing.
let me go find the thread i made so i can give you some info...don't feel like re-typing everything.

 

Heres my post from my thread explaing to someone about how to hear it (this was how it was for my car atleast):

and incase you wanna read through the rest of the thread heres the link...there might more usefull info in it for you: https://www.myg37.com/forums/engine-...nds-fishy.html

 

Ok, so after driving about 15 mile today I havent heard it. Maybe my car was just mad at me for beating on it. Hopefully it doesn't come back.

The other question was about turning the car off. Is it better to turn the car off with the clutch in or out. I notice when it is in it turns off smoother. Also does having the clutch in wear it prematurely like for example sitting at a stoplight. Not that I do it, but I'd like to know exactly what it's doing. Thanks

 

Ha, thought that title was leading to a BAD morning after story about Bangkok!!!!

 

Went over to the dealer today to get it checked out. I went for a ride with the lead mechanic and he said that that noise was normal. I mentioned to him also about when i turn off the car I always have the clutch pushed in because of the awful noise the input shaft makes and he said don't worry about it. "It's a characteristic of the car" he said, so he said it's better to have your foot off the clutch when turning off the car because the clutch will last longer.

Has anyone else heard a loud noise coming from the tranny when your in first gear, pretty low RPM's and you push in the clutch. Sounds like a washing machine breaking down ? I heard it the other day and forgot to mention it to the tech.

 

that clunking noise is supposedly normal... many people on here have noted it... it is a characteristic of the tranny... dunno why but when i first heard it i freaked out... as for the tranny, i've had mine replaced at 7500 miles, having broken synchros and broken cones... and i never drove crazy or anything. i still feel the same way about the new tranny, it just seems like infiniti transmissions are really notchy and i feel like i'm breaking my tranny when shifting into 3rd gear and sometimes the other gears

 

I'm with you there, they're definitely not the smoothest transmissions. But it's ok, I still love my car

 

I might need a new tranny. I'm goin gin this week to ge tit checked out. My
5th gear is grinding.

 

Hopefully they don't give you a hard time. Is it just me or are quite a few people getting their transmissions replaced? For those of you that have, and those of you that might have to get it replaced do you guys ride your car hard. I rag on mine a little bit, but nothing out of this world. Infiniti/Nissan claim to build such a reliable product, yet they've transmission issues with the 6MT G's since the G35 .

 

^^yea thats true...i've seen plenty of people starting to complain about there trannys now.

and i only had the car for less than 3k miles when i had mine replaced...and by the time i broke it in...i barely drove it hard. I don't beat the sh*t out of the car.

 

My tranny has that clanking noise as well, I hear it most when I'm in drive thru's. No grinding so far though.

 

I'm not 2 worried about it. I'm actually happy cause I'll be getitng the JWT clutch and flywheel put in at the same time.
