    Reviewed by Jeremiah Adams

    I wish I could give more than 5 stars. I went in with my car clunking between 1st and 2nd gear and 2nd and 3rd. They gave the estimate and to me the car was not worth repairing but I have to say that the customer service was beyond professional. We talked about my car's estimate but also just got to talking about random stuff. Super friendly staff and reasonable pricing, but to me it was more worth it to get a new car with warranty.

    Friendly staff. Answered all my questions and provided detailed estimates and costs before doing any work. Nobody else in Whitby would tell me how much just to change a clutch.

    Reviewed by Josée McFadden

    Amazing experience! Had a transmission issue and called on Monday afternoon, Denise asked if I could bring it in right away, I said yes. They ran my car through a few tests and saw that a sensor was malfunctioning. Denise asked if I could leave it or bring it back in the morning. I left it. I received a call around 11:30 am on Tuesday and Denise confirmed my issue was a sensor and not the transmission at all. I gave the go ahead to change the sensor and my car was ready for pick up around 3pm. So 24 hours and saving me thousands in what I thought was a new transmission, and I have again a perfect running vehicle. Denise and her staff run an honest and efficient transmission shop! I will definitely go back if I have any future issues!
