Your engine is misfiring if the light was flashing when it first turned on.
A steady light could indicate anything from a leaky or loose gas cap to a problem with the transmission.
AT CHECK: What Does That Mean?
The other day, as I was using the cruise control in my 2001 Infiniti QX4, the cruise suddenly cut out and the vehicle failed to change into fourth gear. I turned it back on after switching it off, waited a short while, and then noticed that something lit up with the words “AT CHECK.” Could someone please help me?
Your trans code is present. Have the dealer check it out. You might perform easy tasks like checking the fluid level while the car is in park. Make sure the level is appropriate. If everything appears good, you should go to the dealer so you don’t get locked up. When the cruise stopped, was the O/D light flashing? That is unmistakably evidence of a trans control issue. Possibly the dash-mounted speed sensor or the entire unified meter.

The rationale for a CVT check light won’t apply to your car. Your vehicle lacks a CVT.
When the automobile starts and runs without issue and the transmission feels as like it is shifting smoothly, the suggestion of a transmission overhaul seems very dramatic. It makes great logic to mention the crank sensor. The starting point is also the least expensive.
Hello, this is my first post. just checking to see if anyone had solid knowledge on this. The search function on this forum was useless to me.
When I tried to turn the automobile on, it just sputtered. I gave it another shot, same result. There was no real cold outside. never before occurred. Despite having over 100,000 miles on it, the engine is in excellent condition. When I googled the “AT CHECK” engine light, I found the image that is linked below. According to the light’s description, it is a “Continuously Variable Transmission, CVT check warning light” (if so equipped).
Additionally, the light has stopped coming on, and the OBDII scanner I used returned no codes.
I then drove another vehicle to perform errands. Later, my father claimed he checked it out and it started without a hitch. I went to check it out, and it also began perfectly. I did read the following in answer to a problem with the “AT LIght” that was similar to mine, but I wanted to double-check with you guys because I’ve never heard of this.

When you turn the key off and on again after the trans sends the motor into fail safe mode due to a power loss, the trans resumes operation until it encounters that failure once more. Slipping transmission or an internal problem may require a total rebuild if the car is acting as you describe.
He asked when the transmission fluid and filter had last been updated. You should have already had the transmission serviced given that you have surpassed 100k kilometers. To determine whether the fluid is good, you should check the level and color. The vehicle’s starting problems could be caused by something entirely different. I couldn’t find anything about beginning problems from the URL you gave at the end of your first post; all I could find was information about how the transmission was causing the vehicle to perform poorly on the road. The next time you see the “AT CHECK” light, hopefully you can use an OBDII scanner to receive a proper code and a better understanding of what is wrong with your car.
Sorry, it was completed at the dealership at least two hours ago. Just out of curiosity, how frequently do you recommend they be completed? The AT indication light barely momentarily illuminated; I guess I’ll just keep it nearby. Otherwise, it might have been an isolated incident.
The conventional A/T (Automatic Transmission) in my 2003 utilizes NISSAN Matic “D” fluid, however i’ve read that the A/T CVT fluid should last a lot longer or never need to be changed. I’m not sure which recent Altima models were the first to use the more sophisticated A/T CVT, but in any case, everything should be included in that service manual.
