I heard lots of people saying the Z have tranny problems, and one of the most is Grinding Gear... I have an 04 Z, I do heard sound when I shift from 1st to 2nd and somtimes 2nd to 3rd, but I'm not sure if is grinding, can you guys explain to me more about the grinding?? Were you still able to get it in gear, or do you have to move it back to netural then shift again, on my Z when I shift from 1st to 2nd I heard a metal to metal rubbing sound, sometimes it get really loud.

Also is When I step on the clucth pedal really fast on 1st to 2nd and sometime 2nd to 3rd, you heard a loud Clunking noise underneath the car, feels like something is loose.

Anyone of you notice of have this problem when your car get warm up and when you step on clucth pedal, you'll heard a ticking noise, if you give a gas, it'll get louder. I can heard my doing this in a very quite place. Is that noraml??

I took it to the dealer but they told me that this is normal. So I wanna see does other Z owner have these problem and did you guys get it fix???

 

I would say you have all the signs of tranny problems to me...
in my car it happen at 5000 or so miles and it was just
that it didnt shift into 3rd smoothly and i mean by smoothly
a metal to metal sound followed by a shape vibration and grinding
im on my second tranny and its fine so far but it only has 1000
miles on it...

 

I don't remember any clunking. My 5-6 grind sounded like throwing a fork in a blender. It would do it every time I shifted at a reasonable (normal) speed. Shifting very slowly would minimize or eliminate it. I only shifted 5-6 about 6 times on purpose, and twice by accident after I first noticed the problem. There was no question that something was really wrong.

And I can't think of any event that would have caused it, either. It just started at 1 AM one night on a perfectly clear freeway drive home from a business dinner.

 

Bran branz33 so you got you tranny replace once?? how did you get the dealer to change it for you?? I took to 2 dealers about 5 times already and they kept telling me the samething. I even called to 800-nissan1 but they didn't help me alot.
