We'll Pinpoint Your Vehicle's Issues With Our Diagnostic Services

Whether your vehicle's check engine light is on or it's not handling as it should, Certified Transmission & Auto Repair has the tools to pinpoint the issue. With an automotive vehicle diagnostic, or car diagnostic test, our mechanics will use the information, and our more than 25 years of experience, to identify what's wrong with your car and what it will take to fix it.


The test equipment we use connects to your vehicle's computer and reads the trouble codes that are stored there. Once these codes, if any, are gathered, the information provides our mechanics with a starting point of what system or areas of the vehicle need further attention or testing.


These tests may require a digital volt ohm meter, pressure gauges, reading a live data stream, or using  bidirectional controls of a hand-held diagnostic scan tool. A proper vehicle diagnostic test in the hands of one of our mechanics is key to discovering what needs to be fixed.


Don't wait to get your car running the way it should, call now to schedule an appointment.

Thorough Vehicle Diagnostic Services

In order to accurately identify any issues with your vehicle, a standard diagnostic test can take an hour to an hour and a half. More complicated problems that may need further diagnosis may take much longer for testing. Depending of the severity of the issues identified, thorough testing may take 2 to 4 hours.


We want to ensure that we use any means necessary to not only identify what issues your vehicle has, but correct them. That is why our ASE-certified mechanics use the most up-to-date special software and vehicle diagnostics tools to find the exact problem with your car.  Contact us today to get a free estimate on your auto diagnostic and repair needs.

Reviews


I took my car in for a clicking noise I heard whenever I would shift into gear which I thought was the transmission. I dropped my car off Wednesday evening, by Thursday afternoon they had called me back letting me know it was my front passenger axle. They had a quote on hand, and were able to order the part overnight. Friday morning the new axle was installed and my car was ready for pickup Friday afternoon. They were fast and efficient, and I appreciate the accomdations they made for me.
