    Heck yes, the eight speed makes all the difference.

    A newer Chrysler 300 with the 5.7 HEMI and 8-speed automatic is faster than my 2007 Chrysler 300 SRT8 with the 6.1L HEMI and 5-speed auto.

    The engine that does so well everywhere else has caused several Gladiator buybacks. The engine idles rough and a P0300 code is either set or pending, and disabled start/stop. And those who have had engine work, it’s the 2-4-6 bank. Revised flashes haven’t helped, it seems.

    I experienced the rough idle early on, but never had a CEL, and it’s since idled much better. I’m gonna say mine way have been bad gas.

    It's got to be the coding, then... or an issue with the tooling or machinery that produces those heads, if they're different from ordinary JL heads.

    The original issue seemed to be a combination of design, vehicle use (maybe weight?), and, yes, the gasoline used. FCA only tested one brand of fuel.
