AT light + hard jerk

[nathan]

Have a Mazda3 2010, just had the ATF changed and still didn't help. Seems only when being throttled that it jerks as the AT light comes on. But if the gas isn't applied then the light comes on and goes off again without a hitch. Even had it parked and the light came on but didn't notice any mechanical changes when it happened. Anyone have the same problem or knows a fix? Thought maybe a sensor giving wrong information that's causing the hard jerk.

Gotta get the computer scanned to see what the code(s) are/is.

Went to had the code read, but it didn't store in the cars computer. No code showed up, I guess because the light only flashed on ?? And doesn't stay on...

you'll need to take the car to the dealer
most scanners will not pull the transmission codes because they are manufacturer specific... if a 3rd party scanner does not include mazda capabilities, you will not find any code
