    Just an observation, the CHT code appears to be automatics with California emissions and the CHC automatics with Federal emissions.

    Interesting, thanks for the observation on that Mike. I still have yet to find a CHS automatic through all of this research. Some of the documentation books/sites aren't right IMO.
