    They had me in and out in 2 days. At first I thought it was a lot of money, but after seeing what they had to do just to get the transmission out I understand.

    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.
