For those of you who were at the West Chester, PA (ECZA) meet, you may have met my Z and me. I have been having transmission issues (3rd gear grind) and I wrote a letter to Nissan explaining my problems. Much to my surprise today while I was at work I got a phone call from Keith at Nissan Tech line. Apparently Nissan IS aware of the transmission issues on 03 models and early 04 models. Nissan assured me that there is a documented fix for the tranny (Replace or Rebuild) and that dealerships are or should be aware of the issue. If you are experiencing any grinding with your transmissions take it to your dealer and have them check it out. If they claim to not know what you’re talking about tell them to call the Nissan Techline and ask for Keith...
