    Has anyone installed the Cobb RMM and hears a ringing noise sometimes? Low speed/ light throttle like just driving around a parking lot. Sounds just like that crystal glass and water trick

    Installed it myself a couple weeks ago and it's been perfect. Super smooth shifts with no added NVH aside from the mild/aggressive-feeling vibration at idle. Did you install yourself?

    Yes and torqued it all to specs

    Hmm, maybe @COBB can run you through some troubleshooting?
