How Do Transmission Diagnostics Work?

Learn about transmission diagnostics, a key process in figuring out what’s wrong with a transmission so that technicians can fix that problem.

What Are Transmission Diagnostics?

The word “diagnostics” comes from the verb “to diagnose”. If you’re feeling unwell, you might go to the doctor who may order one or more tests. The results of those tests give the doctor the information they need to diagnose you with a condition or not. Transmission technicians can do the same basic thing with your transmission.

For most of automotive history, these diagnostic tests were entirely mechanical because transmissions were entirely mechanical. These diagnostic processes were simpler, but less accurate than what the top transmission shops can do today. Modern vehicles have on-board computer systems that help them regulate and monitor the transmission. To diagnose modern transmissions requires high-tech tools. With so much computing power directing, assessing, and recording data on every essential function of your vehicle, transmission shops must have the right tools to interface with these on-board computers.

Diagnosing Your Transmission

There are often several possible explanations for any given transmission problem. Transmissions are more complex than any other auto part except for maybe the engine. If the check engine light comes on, you might have a problem with your transmission, or you might have a problem with your engine. Or maybe something else went wrong.

If your transmission slips into neutral, there could be several possible causes. That’s why you need a transmission shop with knowledgeable technicians and cutting-edge equipment to diagnose your transmission.

Mister Transmission’s Transmission Diagnostic Services

At Mister Transmission, we have industry-leading diagnostic equipment. We can quickly and accurately figure out most transmission problems. We know how to diagnose computerized transmissions. Our expert technicians have access to the right technology to do an excellent job. Our technology allows them to interface with your car’s on-board computer system to determine your specific transmission problems.

What We Do With Diagnostic Information

Often, the first step in our transmission diagnostic process is to connect our diagnostic equipment to your car’s on-board computer. Doing this can give us a code that tells us where the problem is. After fixing any problem that the code indicates, we can take your car for a test drive. This allows us to evaluate your vehicle’s behaviour in real-world conditions. After that, a more comprehensive, hands-on assessment may be required. Diagnostic technology is essential to complete transmission service and repair.
