Technological Diagnostics Service in Barrie, 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.

Find out more about how we diagnose transmission problems and the role of computer diagnostics.

Marcel Heaton
I needed my 1974 MGB clutch repaired. Mr Transmission did a great job and in a timely manner. I thought the price was a bit high but they were the only local company that would work on my car. The staff were knowledgeable and friendly. I would recommend them to my friends and family.

Hats off to Mister Transmission....
Aiden Langford
Hats off to Mister Transmission. Please go here for transmission work or any vehicle service! My 2010 Mazda 3 transmission started slipping at 170K and wouldn't reverse. The team at Mister Transmission were extremely professional and I can't thank Al enough for his kindness and coherent way of explaining what needed to be fixed and why. He made it easy to understand exactly what was wrong with the trans and the logistics behind the repairs. Most shops I've been to for any work on my vehicle have fed me jargon I couldn't follow and I was never entirely sure if they were just trying to get more money from me. Mister Transmission did not do that and my transmission shifts beautifully again (just like new). Once again, THANK YOU! I am beyond satisfied with their work. Don't hesitate to visit them or give them a call.

The staff at Mister Transmission Barrie exceeded my expectations. They were able to chase the electrical issues my car had when the dealer couldn't. Their pricing was fair and my car rides like a new vehicle. I would not hesitate to recommend this shop to you. A. Roussy

Tim Samuels
Just Had my 2015 Toyota Camry XLE 2.5 transmission rebuilt at the Barrie ,Essa Road location.The manager Al was amazing from the time I walked in there feeling hopeless after Jackson s Toyota advised me I would need a new ($8000 ) or used ($4000) transmission as their only suggestion.( paid $153 for that diagnostic). This Camry has just 180,300 km and the Torque Converter was failing ( shudder during gear changes) .Apparently a known issue in the States and I was really hoping Toyota would cover but alas they did not.Al took care of me ( free diagnostic) and even arranged a rental for me at an amazing price ( Bristol) .Thank you Al and your team for a job well done . The car feels great again .You did a great job at a great price and with a personal touch .I highly recommend Al and team to handle any issue you have with your transmission. It s a costly repair no matter what ,because it s a big job and specialized skills needed ,but going to the right people makes it easier and less stressfulFive Stars all the way Thanks again Al

I can not say enough...
Ryan French
I can not say enough good things about the outstanding service and level of trust I have in these guys I took my car in for a new transmission and I received friendly service after the repairs I was shown my old transmission and they explain what went wrong and how the fixed it which was awesome. About a week later I had an issue with my starter I dropped it off expecting to pay $600 they called me letting me know it was an easy fix for them snd not to worry about it which was a life saver. From that point on I’ve used them and trusted their opinions these guys are the best you will not regret giving them your business and like me you will continue to use them I guarantee it

Amazing service! Very friendly, and stayed in contact with me every step of the way. Couldn't beat the pricing and timing was second to none. Al and his staff are fantastic people. I would recommend Mr. Transmission on Essa Rd to anybody. In fact I already sent my boyfriend there and he is just as impressed with their service, professionalism, pricing and timing. Very happy I chose to go here!!
