Have you ever wondered if Autozone can tell you what transmission your vehicle has in it? If your transmission started acting up and out of the blue, wouldn’t it be nice to have a code so that you could try and diagnose what the problem is.

So, can Autozone read transmission codes?

Let’s dive right into it.

Can Autozone Read Transmission Codes?

If you have a check engine light on in your car, Auto Zone may be able to help you read the code and perhaps tell you what it means. They cannot do any type of test of your transmission like a scan. They can connect a scanner to your OBD2 port and see if there is any stored codes in the computer.

If the transmission is shifting properly and there are no codes, then it is likely not an electronic fault but a mechanical type problem. In that case, I would recommend having fluid and filter changed by someone who specializes in transmissions.

You could change it yourself but unless you have special tools like a funnel with a long hose on it, it can be messy and more trouble than its worth.

A transmission specialist should be able to pressure test the transmission for internal problems and let you know whether or not it needs to be rebuilt or repaired internally.

Are Code Readers Free At AutoZone?

If your check engine light is on, and you want to find out what’s wrong before you take it to a mechanic, you can use an OBD-II code reader to help diagnose the problem. If you don’t have one of these devices, many auto parts stores will read the codes for you. AutoZone, in particular, will do it for free and will reset the codes for you once the problem is fixed.

If your check engine light is flashing, however, that is a sign of a more serious problem. A flashing check engine light indicates that your vehicle’s engine is misfiring. Any issues that cause the engine to misfire can potentially cause damage to catalytic converter, which can be expensive to replace. In this case it is best not to drive at all until the problem has been fixed.

How Accurate Is AutoZone Code Reader?

A diagnostic test is necessary to determine the problem with a car if it is experiencing issues. It is not highly reliable to use the free diagnostic test offered by Autozone. An assessment of the car’s diagnostics will only need the vehicle’s computer to be linked to the system’s code scanner. Computers are scanned and identified with which error codes the system has encountered.

All of this needs a person who knows how to interpret the results from the tests effectively. An Autozone employee most likely will not be able to decipher what the problem is, and would leave the customer in charge of solving it themselves.

Rather than getting recommendations from a possibly untrained worker, it is best to get advice from a professional mechanic who can identify what parts need replacing or fixing.

Will AutoZone Reset Check Engine Light?

AutoZone is well known for its extensive selection of aftermarket automotive parts at the lowest prices and is dedicated to providing the right parts at the right prices.

If your check engine light comes on, AutoZone offers free engine code scanning. With this service, you can get a complete report of what caused your check engine light to turn on.

If you have an OBD-II code scanner, you can enter the code in your own time and research what it means. However, if you don’t have one or don’t know what it means, AutoZone can help.

How Do You Clear A Code On A AutoZone Scanner?

You can erase a code by disconnecting the battery for 10 minutes and reconnecting it. The car will automatically turn on all its lights to check that they’re working. After about 3 minutes, turn the ignition key to “start” and let it idle for a little bit. This should clear the “check engine” code in your console.

There are also some AutoZone scans that have a special button that allows you to clear the error codes right on the scanner itself. It’s usually labeled “clear” or “erase,” but make sure it says so on the scanner or else you might accidentally erase something important like your radio presets.

How Long Does AutoZone Diagnostic Take?

To conduct a diagnostic, you will need to visit your nearest AutoZone location, where the store’s technicians will ask you what problems you’re experiencing with your vehicle.

After that, they will use their diagnostic equipment to determine the problem.

If they can’t find it, they may need to run more tests on your car by removing components for access or testing.

In most cases, a diagnostic test can be conducted in about an hour and a half. A more complicated problem that requires further diagnosis and involves removal of components for access or testing may take two hours or more; depending on its severity and the extent of its underlying issues.

What Can A Car Diagnostic Test Tell You?

One of the most common questions we get from customers is, “What does a car diagnostic test tell me?”

A car diagnostic test is an inspection of your vehicle’s onboard computer. It examines about 100 parts of your car, including the engine and emissions systems, to make sure they’re in good working order.

In general, most modern vehicles are equipped with internal self-diagnostic systems that alert you to any problems or malfunctions. If something’s wrong with your vehicle, your check engine light should illuminate on your dashboard.

That check engine light can mean any number of things — anything from a loose gas cap to a more serious problem that needs immediate repair.

If you see this warning light illuminate on your dashboard, you should take it into any Firestone Complete Auto Care location for a free courtesy check. Their technicians will perform a quick scan on your car and let you know what the problem is, so you’ll know whether or not you need to make an immediate repair or if an oil change can wait until next week.

Can Car Diagnostics Be Wrong?

Can car diagnostics be wrong?

The short answer is yes, they can be. Sometimes, these faults are not actually faults at all and other times, they can be a fault with the software of the diagnostic machine itself.

When you take your car to the garage for a diagnostic scan and they tell you that it has a specific fault, you don’t want to doubt them. They’re the experts after all and you probably don’t even know how to use the machine yourself. However, there are some circumstances where you might want to question what’s being said.

Here are some examples of why diagnostics can be wrong:

They’re not plugged in properly – sometimes, if the diagnostic device isn’t connected properly to your car’s computer system, it can cause false readings or show faults that aren’t actually there. This could be due to a wire coming loose or it just not being connected properly in the first place. If this happens more than once with your mechanic, then perhaps consider taking your car elsewhere as they clearly aren’t connecting it up properly each time!

The sensors need replacing – if your mechanic is telling you that various sensors need replacing and you suspect he’s trying to rip you off, you may have grounds to argue otherwise.
