For recently few days I am facing a big problem which is AT signal !

my car suddenly shows AT signal when slowing down or coming to a stop and car make a high jerking and speed done both ahead and reverse


here mechanics are not very expert about Mazda. They are telling me to change the Transmission Box directly

but I can feel that no need to change transmission box cause I can easily hit 160 ~180 kmph speed

and the At signal not showing in running high speed

Can you take a picture of the light that's coming on and post it?I just and a 2005 Mazda 3 that had the transmission light on and was slamming into drive and reverse and was in limp mode. At that point I couldn't talk to the transmission computer it ended up being a bad transmission computer. Have you had it scanned for codes yet?

I saw it so do you have the exact code numbers not code descriptions?That would be a letter followed by a four digit number.
