I've noticed recently that my mazda 3 on cold starts would show the at warning light. When I start it, it normally flashes it for a few seconds then disappears. Then when I pull it out of the garage, the at warning light shows. What I do is I immediately shut it off, then start it again, and the warning light disappears.
It has happened to me twice already so I am a bit concerned as to why it is appearing.
I checked the transmission fluid it is still very red, no burned smell. I am thinking if this is a solenoid problem.
I plan to have the code checked, but I wonder if it is because I immediately move the car around 5-10 seconds after I start the engine. Will be a factor to the issue? Also shifting from reverse to neutral to drive to neutral to reverse and back to drive would also cause a problem to the car?(It's how I pull out of my garage) if the car is still cold?
Based on the symptoms, Does it have a big chance that it really is the shift solenoid or is there another problem? I want to at least prepare myself if it isn't a solenoid problem.
