    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.

    Reviewed by Rick N.

    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.
