AT light comes, and car jerks

[KevinM3]

Hi there,

Been happening everyday now, but only a few second stretch while I’m 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.

Looking for one now.. but seems hard to get a hold off.
