The automatic gearbox has malfunctioned in some way, making it impossible for the computer to determine whether it is in gear or not, which prevents the engine from starting. To get it diagnosed, you must take your automobile to a dealership.

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.

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.
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.

Can I drive with a warning from an automatic gearbox?
Even though the car might not drive any differently with the light on, you should still have it looked out as soon as you can to prevent more damage. Long-term driving with this warning light on is likely to drastically shorten the transmission’s lifespan by wearing it out. Some automobiles may enter what is referred to as a “alimp home” mode. The vehicle’s top speed will be restricted by the “limp” mode to lessen the burden on the transmission.

What are the symptoms of a failing transmission?
1. Failure to change directions
You are most certainly dealing with a transmission system issue if your car refuses or has trouble shifting gears. Your car might not be shifting gears because it has low or the wrong kind of transmission fluid.
2. A burning odor
Visit a mechanic as soon as you notice any burning smells coming from your vehicle. This smell could mean that your transmission is overheated or that the fluid is scorched and old.
3. Sounds During Neutral
Strange noises emanating from your car when it is in neutral are a solid sign that your transmission may be having problems. If you’re lucky, the noises might be a sign that your automobile needs new transmission fluid, which a mechanic would flush and replace.
On the other side, it can also indicate that your car needs to be replaced or need further maintenance from a qualified auto mechanic.
4. Slipping Mechanisms
When your gears suddenly shift while you are driving, it is not only unsettling and disturbing but also dangerous because it is never advisable to operate a vehicle with a slipping gearbox. If you hear the engine roaring while shifting gears, your transmission has slipped. It’s frequently equated to having no apparent traction on the road and feeling like you’re driving over ice.
A delay in acceleration, odd noises, and a generally harsh response when you try to shift gears are some other signs of slipping gears.
Fifth Drag Clutch
When you press the clutch pedal in your car, a dragging clutch does not release the clutch disk from the flywheel. When changing gears, this problem causes the gears to clatter and the automobile to move. The most typical causes of a dragging clutch are mechanical problems or clutch misalignment.
6. Fluid Leaks
One of the simplest transmission issues to diagnose is leaking transmission fluid. Tell your mechanic to check the transmission fluid level and look for any leaks if you find a crimson, sweet-smelling fluid underneath your car in a garage or parking lot.
7. The Check Engine Lamp
Your dashboard’s check engine light may be triggered to signify a number of automotive problems, both small and major. But if determining the problem’s source is crucial, be sure to have a local specialist take a look.
8. Milling or jiggling
Any form of grinding or shaking that happens as the gears shift is more frequent in vehicles with automatic transmissions. This is frequently a solid sign that there is an issue with your transmission. When this occurs, it’s crucial to get your car checked out by a mechanic as soon as you can.
9. Strange Sounds
None of the humming, whining, or clunking noises are pleasant to hear in a moving vehicle. There are a variety of reasons why your car can be making odd noises, but only a qualified mechanic should attempt to fix them.
10. Not responding
If you try to shift gears in your automobile and it doesn’t respond, especially when you go from park to drive, your gearbox is probably broken and you require transmission service.
When the AT light illuminates, what does that mean?
The “Automatic Transaxle” light is indicated by the AT light in Mazda automobiles. It is best to pull over as soon as this light illuminates and take the automobile in for maintenance.
When the car is restarted normally, the light would turn out, but you can be sure that it would come back on shortly. Ignoring it could harm your automobile in the long run.
