Check Engine Light Scan & Diagnosis

Mister Transmission has been such a wonderful experience! Absolute speechless.. three different vehicles with transmission problems and each one received outstanding service. Thank you Mister Transmission Tom and Alix Nicholson

I couldn’t be more impressed with the service at Mr. Transmission in Barrie! After taking my car to a dealership I ended up with a substantial quote to fix the transmission issue. A friend suggested me to take my car to Mr. Transmission and I’m so glad I did. They performed a thorough diagnosis and found the issue that the dealership completely missed. Mr. Transmission team was professional, honest, and clearly very knowledgeable. I really appreciate that they were able to fix an issue on the spot without even charging me. If you’re looking for a place that truly knows what they’re doing and puts customers first, I highly recommend Mr. Transmission. Thank you again Jason for your expert help—I’ll definitely be back if I ever need transmission work done!

My van lost power on the 401 driving through Barrie on a Friday night. I had it towed to Mr Transmission, they fixed it on Monday, they reported to me it was a blown line on the transmission. Faster and much cheaper than I expected. Great service from Jason and the team.

The front person and mechanic were awesome. Checked oil level, added and identified the problem quickly. Was very impressed with the service received. Do recommend checking them out if having issues with your transmission

I was in the area and had an issue with my Hyundai Tucson shifting. I called and the Manager - Jason offered to squeeze me in. Jason listened to my complaints and with his expert trained staff were able to diagnose and fix the problem immediately. They had me on my happily way in no time. Thanks guys!

Jason provides excellent service and you can tell that he genuinely cares. There is no question as to where I will be bringing my family's 2 vehicles for any transmission related issues.

We have used Mister transmission's services more then once and they have been exceptional every time. This past visit, they found an issue with a component that was rusty and ceased up. They lubricated and freed up the piece which solved the issue. When it comes to transmission issues we wouldn't use anyone else. They are fast, reliable and honest with great communication.

I had an amazing experience at Mr. Transmission, thanks to Mr. Jason! He was incredibly knowledgeable and provided excellent customer service. The free transmission diagnosis they offer is fantastic and helped me understand exactly what was going on with my vehicle. Mr Jason took the time to explain everything clearly, and I felt confident in their services. I highly recommend Mr. Transmission for anyone in need of honest, professional transmission repair. You won’t be disappointed!

Super Friendly and Super Quick! Booked a date to drop my car off with Jason and they seemed pretty busy with all the cars parked out front. The diagnosis was free and the techs did an amazing job and pointing what the issue with my car was. There was full transparency and super nice the whole time and for a place so revered the time to get my car back was astonishingly quick. 100% would recommend this place to everyone.
