Eileen P
It’s unfortunate that we had a transmission issue with our Ford Edge with only 41,000 km and being just 7 years old, but we couldn’t be happier with the way Mr. Transmission looked after us. Mark was absolutely great to deal with, friendly, professional, honest, and kept us informed throughout the process. It made a frustrating situation so much easier. Thank you to Mark and the team at Mr. Transmission for taking such good care of us. We would definitely recommend them! Joe & Eileen

Dave In
This shop is great, they worked on my daughter's 2013 focus in 2017. When Ford would not honour their warranty. It is still going strong. I was told the transmission will out live the car. Well yes. It's time for a new veh with. Worked on my 2003 F150, great work, now my 2010, once again great work. They took time to find a miss, in the truck. I'm a car guy, and know shops that do great work. Yes everyone is never happy with the work. But for me there is always two sides.

Had to get my transmission...
Aidan Hennebry
Had to get my transmission redone on my 2017 Dodge Grand Caravan at 140k clicks. Sucked. My local shop quoted me a little over $8,000 for the repair. I decided to call around. Mister Transmission gave me tons of information, answered my billion questions (even before I'd committed to becoming a customer), were prompt in getting my van dealt with, and even gave me better parts than my local shop had quoted me for... all for $6,500. How they did all of that for cheaper than my first quote I do not understand (other than the fact that: They are the only transmission shop in town, and all other shops would just bring transmission rebuilds over here). 10/10 would return to in the future (but hope not to have to). Can't recommend them enough. Mark and the gang: Thank you guys for the incredible service.
