I think Nissan should of out-sourced their manual trans. from Honda, you never hear about in quality problems with their manual trans. & everybody talks about how smooth they shift. My 97 T-56 6speed in my WS6 T/A shifts a whole lot better " no issues" & that was one of the borg & warner designs from the early 90s. The 370Z trans. design is 12 years newer but less effective.
