Technological Diagnostics Service in Hamilton, Ontario

Advanced Technology for Assessing Transmission Problems

At Mister Transmission we have access to leading-edge diagnostic equipment, enabling us to offer you the fastest and most accurate findings about what’s going on inside your vehicle’s transmission. Today’s vehicles come equipped with complex computer systems. Our technology can talk to your car’s computer systems to find your specific transmission problems.

The first step in assessing your transmission involves your technician connecting the diagnostic equipment to your vehicle’s on-board computer. This will produce a code stating where the problem lies. Next, the vehicle is taken for a test drive so that we can monitor its behaviour in real-time. While more comprehensive and hands-on evaluations may yet be required, technology is an important tool in determining the right starting point for further investigations.

Marijane Doyle
Justin at Mr. Transmission on Upper James Street is honest, professional, and truly stands behind his work. When my engine light came back on just 10 days after the repair—even though I had driven the car only twice—he asked me to bring it in right away. He quickly determined that the brand-new replacement part was defective, replaced it, and charged me nothing for the additional diagnosis or repair. That kind of honesty and commitment to customer service is rare today. I highly recommend Justin and his team.

A very good experience. Free diagnostic, free road test, and free honest information. I was informed the issue with my car is not the transmission but they are unable to fix the problem. I appreciate the honesty most of all.
