Car Troubles? Learn How Technicians Diagnose Problems with Your Transmission and Other Systems

By Mister Transmission

The digitization of your car goes far beyond wirelessly connecting your smartphone to a sound system. Diagnosing transmission problems in modern vehicles is a high-tech affair

At one time, diagnosing transmission problems involved a bit of guesswork. It was an inexact sciene that was often time-consuming and potentially costly.

Fortunately, automotive and auto repair technology have advanced rapidly over the last decade. Now there are incredibly sophisticated onboard computer systems in your vehicle, and high-tech diagnostic tools mechanics use for car trouble diagnoses. The digitization of your car, truck, or SUV ¬¬goes far beyond wirelessly connecting your smartphone to your vehicle’s sound system or the other electronic features you see on your dashboard. Underneath the hood, there is a lot of computing power directing, assessing, and recording data on every essential function your vehicle performs.

 

 

 

 

Diagnosing Transmission Problems Quickly and Accurately

For example, when a Mister Transmission technician hooks up a scanner to your car’s computer system, within seconds, he may read a diagnostic trouble code like “P0732,” which refers to an incorrect gear-two ratio. In plain language, this means the transmission didn’t shift into second gear as it should.

Based on this information, a short test drive is required to monitor all of the input and output speed sensors data, as well as the car’s engine control unit which is responsible for sending and receiving that data. Once complete, our certified experts can pinpoint the reason for the car’s problems, and determine if the problem is the transmission or a digital malfunction between the car’s computer and the transmission.

The key thing to remember is that a transmission is a very complicated and sophisticated piece of equipment – especially those installed in newer vehicles. There is no “one-size-fits-all” solution to transmission problems, and anyone who suggests otherwise is misinformed, or they may be trying to take advantage of you. Most importantly, they may be compromising your safety.

We Will Never Compromise Your Safety
At Mister Transmission, we always put our customers’ safety first, and we guarantee our work. It’s how we earned a nationwide reputation for honesty, integrity, and value. Our experienced, trained technicians are knowledgeable about the computer systems in any domestic or imported vehicle type, and how to diagnose car problems with a computer.

We strive to provide our customers with accurate information, to keep transmission repair costs as low as possible, and to get their vehicles back on the road quickly.

For more than 50 years, Mister Transmission has kept Canadian motorists on the road by ensuring the transmissions in their vehicles are in tip-top shape. If you have a question about your transmission solenoids or want to book a service appointment, contact the Mister Transmission service centre nearest to you.

I brought my 2012 Honda Civic in after another shop told me I needed a total transmission replacement. The car was in limp mode, wouldn't move in drive, and was revving erratically. Gus and Ray were amazing. They actually took the time to diagnose the real issue instead of just guessing. It turned out to be the accelerator pedal and a need for a transmission fluid service. They saved me thousands of dollars and got me back on the road. Professional, honest, and highly recommended.

Highly recommend Mr transmission. They worked with me in every way possible and were straight up about everything that needed work. And didn’t push to do work that I could hold off for a while. They were very accommodating to me to work with in my budget. Even talked to manager and also talked to the technician. To help me understand what work needed to be done.Very happy customer and will recommend to all my friends for sure.
