My automatic 04' Mazda 3 has a problem... When the car is cold(sitting parked overnight) I will start it up to head to work and the AT light will come on. The car will jump hard when trying to put the car in gear. Once the car is in gear it drives fine even though the AT light is still on... If I drive the car until the thermostat shows that the car is warm and then turn car off and back on the AT light is gone and car does not jump when putting in gear. So my question is, why is my AT light on only when the car is cold? and why does the car jump when putting in gear but drive fine after that?
Note: I changed my tranny fluid and filter to solve the issue and it did not help.
