I put my car into service to get TSB on real axle clicking noise.
The noise is now gone..BUT, after I drove the car for a while
I started to hear this rattling noise (I think from tranny??)
when idle, when I start to accelerate into gears, or when I don't shift smoothly (i.e. letting go of clutch too early thus at the point of jurking)
And the noise dissapears after i reach cruising speed..probably after 3rd gear.

I did a search, and it seems like most people are having this problem when
turning on/off the car ONLY.
Do you think dealer messed up when the were doing TSB..or something like that???

 

hmmm... I just got mine fixed today but i havent heard anything tomorrow ill check it out tho and get back to you

 

seem like the exhaust/y-pipe hitting the under body of your car.

 

I think my car has that clicking noise that you went into service for! Did it only happen when you just started off from a stop (maybe 5 mph)? Nissan has a TSB on this? Please let me know, I'd love to get it fixed.

 

Yup that's exactly what my Z had. Go get it fixed at your nearest dealer immediately.
There's TSB for it, but if you just talk to the service manager and mention
clicking noise, they'll know right away and fix the car.
