Technological Diagnostics Service in Windsor, 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.

First of all a huge thank you to Julie for all of her help and expertise when dealing with the transmission rebuild on our Dodge Grand Caravan. She is very professional, knowledgeable and a pleasure to chat with. I wish all business's had staff like her. We had a great experience at Mr. Transmission and I will definately refer my friends. The mechanics were very quick to diagnose and only recommened what was needed. They were great in keeping us up to date with the progress of our repair. Thank you all for giving us piece of mind with our vehicle.

Mister Transmission immediately welcomed and reassured me from my very first phone call. Everyone was incredibly friendly, explained everything thoroughly, and made sure I knew there were options for repairs, which meant a lot to me. A special shoutout to Julie for her amazing customer service and for being so incredibly helpful throughout the entire process. She truly went above and beyond. They noticed multiple issues with my vehicle very quickly, things that previous shops never mentioned. Other shops kept giving me vague “maybe” fixes, but Mister Transmission was straightforward, honest, and thorough, covering all the bases without any pressure or scare tactics. Within two days, my truck was fixed and running amazing. I went in thinking I needed a whole new transmission, and thankfully that wasn’t the case at all. I will absolutely be returning for future work and will be making them my go-to shop for repairs. I’ll also be recommending them to anyone I can. Thank you all so much for your amazing work, it’s genuinely appreciated. I’m no longer scared to drive my vehicle!

Great experience. Julie went above and beyond with communication, and I wish I could get customer service like this in more place. The guys in the garage got the car diagnosed and fixed the issue at far less cost than I expected and did some simple preventative maintenance to one of the of the sensors. Great work, and highly recommended.

I had a great experience trusting Mr. Transmission to make the rebuild of my 2020 Ford explorer Transmission. I was desperate about the car issue at the beginning, because it was a serious and costly issue, but Julie was very regardful, she took the time to explain all the costs and procedures until the car is fixed. She also was very patient with me and my husband because we had to take our time and figure out if would be worth to fix or just sale it the way it was, once we decided to fix, it was a matter of 8 days to have the transmission completely rebuild. The car is working perfectly as it was before the issue and I really recommend them to take care of any transmission related issues. Thanks Mr. Transmission

I recently brought a Cadillac CTS into Mister Transmission for a quote on an issue I was having with my transmission. The team answered any questions I had and were very thorough with the explanations that they had given me for the diagnosis. They also offered very competitive prices to address this problem. I'd like to give a special recognition to Julie aswell who was very helpful with the process. I will definitely recommend any friends or family to this shop if they experience any car issues.
