    Default AT light comes, and car jerks

    Hi there,

    Been happening everyday now, but only a few second stretch while Iím driving.

    The AT light would come on, and my car would jerk but then it goes away after a few seconds.

    Any ideas? Did a quick look through in the forum, and a TCM component seems to be brought up.

    I have a 2012 Mazda 3 2.5L Auto which is currently at 195k km

    Thanks!

    Check the turbine input speed sensor first on the side of the trans. P/N FN11-21-550

    But ya, they are know for needing TCM's.
