I thought my car was not effected by tranny problems, but it happend. My car has 17,000 miles and it started to grind when I shifted from 2nd to 3rd. Took it to first dealer, and they told me that "you can't shift fast in these cars." It was so funny, he told me that our tranny is not designed to shift fast and that if you shift slow, it won't grind. So I left that dealer and went to another one. Here they treated me nice and they told me that they will replace my tranny. So what I am trying to say is that choose the right dealer. Some of them are just idiots, and some of them are really good.

does the grinding go away if you shift it slower ?

 

Ya, it goes away if you shift slower.

 

report the first dealer you went to, to nissan north america. That is complete BS to be treated like that.
