    Reviewed by Chris Walker

    Very friendly and fast service. After the main service was completed, they walked me through a couple other issues my vehicle was having to see if I wanted to schedule future services and repair.

    Reviewed by Marvin P

    Manager Bob is very accommodating and gave me piece of mind. He drove my car to check if there is any issue. Found out that the car is absolutely fine. Didn't charge me anything which is really awesome. I recommend him if you find any transmission issues in your car.

    I was pretty upset about my vehicle breaking down. The communication of what was happening with my vehicle was amazing. The people here took care of the repair in a very quick manner. I was back on the road in no time. The cost of the service was more reasonable than other places in comparison. I would definitely recommend to anyone who needs servicing.

    Reviewed by Dan Stewart

    Very knowledgeable and helpful. One of our fleet truck was not shifting correctly. The shop doing our fleet maintenance diagnosed it as a transmission problem. We brought it to Mister Transmission who diagnosed the problem as a faulty TPS sensor on the engine. Back to our mechanic who replaced the TPS sensor, the transmission still wasn't shifting right and they once again diagnosed a faulty transmission. Back to Mister Transmission who diagnosed that the new TPS was not calibrated when installed. We found new mechanic who calibrated the new TPS - problem solved.
