Research notes

Caveats and conflicts (6)
  • Manual is for 2008 not 2007. It does not say which code is the 5-speed; M15M-D is inferred as the 5-speed (same naming as Mazda R15M-D and S15M-D 5-speeds on Wikipedia) and P66M-D as the 6-speed.
  • Manual is for 2008 not 2010. It does not say which code is the 5-speed; M15M-D is inferred as the 5-speed (same naming as Mazda R15M-D and S15M-D 5-speeds on Wikipedia) and P66M-D as the 6-speed.
  • Manual is MY2008 only; 5-speed vs 6-speed assignment of M15M-D/P66M-D inferred from the code, not printed in text read. Year differs from the manual's MY2008.
  • Manual is MY2008 only; 5-speed vs 6-speed assignment of M15M-D/P66M-D inferred from the code, not printed in text read. 2008 is covered by the manual; 2006 and 2009 assumed same.
  • Mazda code ambiguity: 2005MY box is M15M-D, 2006 workshop manual list shows Y16M-D. Not confirmed which is the 6-speed or whether the U.S. 6-speed differs from a 5-speed sold elsewhere.
  • Same ambiguity as 2004 row.
