Gears Scratch/Grind When Shifting Gears
My '09 G37S manual transmission is scratching/grinding when I shift gears, mainly 2nd, 3rd, and 5th. The car has 31k miles. Its under the Certified Pre Owned warranty which I I'm pretty sure covers the transmission. Will they give me a new transmission just because the gears scratch? How should I approach the service people?

I agree. Sounds like synchros are bad. Take the car in and let them look at the gearbox before you lose a gear!

so difficult -- because all observations are subjective. in all honesty, I had the same concerns about my transmission in going to 2nd, 3rd, and 5th. my dealer took it so seriously that they ended up removing the tranny, opening and examining all the synchros. while I appreciated their "go get it" approach...it turned out that my gearbox was just fine. our boxes are just...rough around the edges.

my in law has an 03 g coupe and his shifts much smoother he says (he tested out the gearbox on my car)
but from what i have heard from dealers/people in the forum is that our tranny is just rough..

I see that several G37 owner's have had gear grind. I have noticed it in my '08 going into 5th gear. This only happens when it's cold, after it warms up it's smooth. I have an appointment with Infiniti tomorrow. The service tech said that it's probably the cluitch, but I believe it's the 5th gear syncro. IMO, if it were the clutch, I would have the problem in more than just the one gear and the grind wouldn't go away when it warmed up. Appreciate any feedback.
