Hi....

Over the course of the past week or so my AT light has came on/off twice, both times now it came on when I started my car after it's been sitting on the road overnight and both times the light went off after driving for about 20 minutes then parking, shutting off the engine, and leaving my car for 20 minutes before restarting...

As it's happened the two times, I'm expecting it will happen again and I'm afraid of an expensive repair if I ignore it or wait till it comes on permanently... Also I bought this car a little over a year ago and still have 8000 km on my after market warranty that I got with it, so I'm hoping that if there's a problem that maybe the warranty can cover it if it's caught soon enough..

Also I don't know if it is related (really not a car guy!), but I've noticed that at low speeds when I make sharp turns (like in some Tim Horton's drive-thrus!) that my car makes a very loud squeaking noise?

Also I have a 2004 Mazda3 and it has about 160,000 km..

Thank You

the light indicates an electronics fault in the transmission... you will need it checked at the dealer
whatever it could be, it could be cheap or expensive to fix... it's not something you want to find out after your warranty is gone

Thanx for the replay..

Anyway I just got back from the dealership and they said they couldn't find anything wrong with my car that would cause the AT light to come on... So they suspect a faulty PCM, replaced at $1800!! Woah!! For now they just reset the computer and if the light comes back I'll have to get that done. Man I hope my warranty will cover it!!!
