My transmission was replaced at the infiniti dealership because they said Fluid Burnt, Metal Shavings in Oil and Synchro was defective. So my question is how can i prevent it from happening again in the future. Why did they go bed at such a low mileage 41k. Do you think it will go bad again at 82k after the warranty expired? Btw i have 08 6 Speed.

Thanks

 

Did you change the fluid?

 

I bought my 08 g37s used back in october and the trans had to be replaced immediately when i bought it at 21,xxx miles!!!

 

Thats crazy, i mean at least they replaced it, hopefully nothing goes wrong from here on in. Ive seen a few 6mt with 80k miles, none that seem to have any issues so hopefully it was a car specific thing.

 

What felt wrong with it before you took it in for inspection?

I have some issues with my tranny, I'd like to know.

 

Yeah. When I think I have something going on with my syncros also. When I press the clutch in between 4-5k rpms in first I can here like a turbo spooling sound. Gonna stop by the dealer this week and see.

 

my trans was grinding going into 2nd. took it back to the dealer and they replaced the trans, cutch assembly, and flywheel

 

bought a brand new g37s 2010, i had my transmission replaced at 13,000miles. Since day one upon starting the engine i heard like a whip cracking noise on the first 2 crank revolutions. Then when turning the engine off, i heard a clunking noise the last 2-3 crank revolutions. all of that kinda threw me off, but wasnt really enough to cause a huge concern.

then when in idle, id hear a rattle noise- not like anything with an exhaust, or a heat shield- but inside the bell-housing of the tranny. brought it back multiple times to the dealer and was told this is a "typical g37 noise." Now i knew better... this was either a throw-out bearing/input shaft bearing or a clutch issue.
LONG STORY SHORT- the noise got louder and louder on idle, and started appearing around 1,000rpm to 1,900rpm when accelerating. became annoying and loud and embarrassing.
i brought i back few more times. they changed the fluids, they did the 2009 ECU remap, etc- even changed the shift ****. all the time im telling them they are wasting my time, and dealership time- ITS THE TRANNY!

after opening a consumer affairs report, finally someone at the dealer test drove a similar car like mine with similar miles and called me and told me that car didnt make this noise and they are ordering me a new tranny. (said they dont fix or work on tranny's- just replace them)

now, i have a new tranny, and no noise. - they never told me what it was exactly.
