Has anyone had this problem or know what it is? I noticed today that when in 1st gear I reach 4000 RPMs, my transmission (or so I think) is making a rattling noise.

If I need to have tranny work done, will I still be covered under warranty if I've only got 40,000 miles? Thanks

Sven (hoping it's nothing too serious)

 

Noisy transmissions are pretty common in the Z so it's hard to say if you have a real problem or not. Since the drivetrain warranty is to 60,000 miles, bring it to the dealer and have them check it.

 

Thanks, I'll have to bring it in then.

 

I've got an 04 G and my tranny was unusually loud in 1st gear too. It also grinded going into 3rd and 5th. I took it to Infiniti and they replaced it under warrenty. They had my car for 2 weeks but they gave me a loaner.
