    Friendly, knowledgable guys. Highly recommend Mister Transmission to anyone looking for repairs to their transmissions. My vehicle has a CVT transmission with issues. I was told by the dealer that i had to replace mine, and nobody could fix it . But I come to find out that Mister Transmission can and will rebuild it. Suprised as I was, in the end I saved about $1000. Thank you again

    Very honest, I trust them to tell me truthfully about issues with my vehicle, and when I can put off repairs. Never have to wait long for my repair to be completed, and I find the pricing quite fair.

    Highly recommend this shop!!! After being told by a couple of local shops that I needed a new transmission.(2400$) I wanted another opinion. These guys are always very helpful. Always explain exactly what’s wrong. They showed me my faulty linkage and explained that my transmission did not need to be replaced. Thanks to them I saved 2000$ If you have any question regarding your vehicle don’t hesitate to call these guys

    I highly recommend this shop.They quickly diagnosed the problem with my commercial truck. They showed me the broken chunks of metal and then gave me a few options to move forward. The truck returned to work a full day ahead of my expectation. The workmanship was great and the pricing was very reasonable, I would not hesitate for a moment to tell friends and family to use this for fast, efficient service. John Kenney
