Just a shout out to...
Allan Sage
Just a shout out to Mark and Tyler of Mister Transmission for some work I had done on my car this last week. Mark did a thorough check of my problems and Tyler was able to order the correct part to fix the problem. This is a 24 year old car and I was pleased that between the two of them they were able to get me back on the road again at a very reasonable cost. THANK YOU GUYS Sandy & Allan

Mark and the crew are absolutely phenomenal! Such a dream to work with. Got my transmission rebuilt on my Silverado two moths ago; already put 10,000 miles (~16,000 km) on it, towing and everything and it’s performed absolutely flawless. Turnaround time was amazing and I will always recommend them!

Paul Baker
Hey, I had a great experience with Mark and his crew. They are all professional and really know what they are talking about. I've had great experiences with other Mr. Transmission shops in the past as well, but this location has been the absolute best! I got an honest diagnosis and the most fair suggestions to mitigate the issues with my transmission and other aspects of my vehicle which were affecting its performance. I will be returning for any further work which will have to be done. My experience is getting a true knowledgable professional to do any service and repairs/replacements is the most cost effective way to go, especially considering the complexities of today's modern transmissions. I have faith in this establishment to do their utmost in providing the most accurate assessments and means of solutions available. They all have your best interests in mind and are accommodating.
