Wayne King
One of the best experiences I have at a repair shop. I had transmission problems that I expected would cost hundreds of dollars to fix. Ended up it was just some rust seizing a linkage - they cleaned it up and didn't even charge me anything works fine now and I couldn't be happier - will be recommending them to everyone.

Brought my Nissan in for what I and many thought was a transmission issue. The team at Mister Transmission Test drove it and checked it over and determined it had an issue but not the transmission. They handed back my keys and didn’t charge me. Thank you, Jason for the great service!

Dirk Bag
I have waited a full year to leave a fair review.Got me a 2018 Ford F150 with that faulty 10 speed that started to act up. I called 2 or 3 transmission shops that quoted thousands above, 1 nearly doubled what this shop quoted and 1 shops that said they will not work on this transmission... unbelievable..lol.Took it to Mr. Transmission and got it rebuilt. This truck runs like new now, better than new imo. I even went to test drive a newer 2020 model with much lower kms to compare and that one didn't shift as well as my 2018.Amazing transmission shop!Thank you!!

I had a fantastic experience with this team! They are incredibly skilled, efficient, and truly go above and beyond. My caravan had major issues, including a complicated transmission problem, and they took the time to thoroughly diagnose everything with great attention to detail.What really stood out was their transparency and communication throughout the entire process. They understood how important my van is for work and made it a top priority to get me back on the road as quickly as possible.Thanks to their expertise, my van now drives like new. Huge thank you to the Barrie team and management—you clearly know your stuff. Highly recommend to anyone needing reliable, professional transmission service!

Ryan Wright
Overall, best service I have been provided with in a long time. Jason helped me with my transmission issue. I had my vehicle at the dealership which told me $12,000 for a repair. I then had the vehicle towed to Mr. transmission. Jason and his crew did a free multi point inspection and found the exact issue and And they fixed it up for me and got it moving once again thank you to Jason and your team at Mr. transmission for providing a well trustworthy service. Much appreciated. Definitely will be recommending to anybody who wants proper transmission service.
