I am starting this thread for those who are having issues with the 09G/09M transmission. Ideally, I would like to see this be an all encompassing thread relevant to the mechanical, interchangeability, and technical aspects of this transmission. The following vehicles use this transmission; this is not exhaustive so there may be some missing applications, especially with the non-US vehicles and those very new.
