Computer and Internal Diagnostics

Our advanced computer and internal diagnostics are the next level of diagnostics that ensure AAMCO technicians will only fix what needs fixing. Many transmission problems start in the computer system of today’s highly technical, computer-controlled vehicles – your transmission receives the wrong signals from your vehicle’s computer system. The AAMCO Computer Diagnostic Service is performed to determine if an electronic component is affecting your transmission’s shifting or overall performance and includes:

Using a computer system scanner to retrieve any trouble codes and to determine the probable cause. All critical computer systems in the vehicle are checked for trouble codes because a variety of systems could cause driveability issues.

Reviewing the computer system data against our proprietary AAMCO technical database – the most extensive transmission computer diagnostic source available anywhere.

Connecting the AAMCO Kwiktest™ PlusBox to see whether the problem is inside or outside of the transmission in the computer system.
Your certified AAMCO center technician will also:

• Check the electronic components
• Check the solenoids and sensors
• Check the wiring that affects the transmission, solenoids, and sensors

Your AAMCO certified technician can then determine if an electronic component or part needs to be replaced, and make a recommendation for whatever service is necessary. It is our comprehensive diagnostic approach that sets AAMCO apart so that you only get the repair you need and your car, truck or SUV is back on the road as soon as possible.

For nearly 60 years, AAMCO Centers have become the trusted experts in the diagnosis, service, and maintenance of transmissions. Call AAMCO first. Before starting any repair, we will perform our extensive TranScan diagnosis on your transmission. And for over half the cars we service, we find only a minor repair is required. Call a competitor or local independent shop, and they may quote you a price for a transmission that you may not need!

If your transmission does require repair, AAMCO will rebuild your transmission right – not install a cheap junkyard unit. We will back it with the strongest nationwide warranty in the business – from our basic no-questions-asked nationwide warranty to our available iron-clad lifetime warranty!

Fixing your transmission problem right starts with diagnosing your problem right! That’s why we will perform our exclusive multi-point TranScan service on every car before we do any transmission repair.

We have the technology and expert diagnosticians to pinpoint the root of your transmission problems so we only repair what needs fixing and nothing more. Over half of the time, we’ll discover your transmission only requires a minor repair. It’s why AAMCO is the most trusted name in transmissions and has been for nearly 60 years.
