Hamilton Upper James Rating 4.7/5 - 42 Reviews

Written Reviews

When I received the car I noticed there were multiple spots of dirt/grease on the light grey headliner and on the A pillar, when I parked it at home I opened the hood and seen a few lines disconnected that should have been connected as I was investigating why my car sounded like a go cart when accelerating - did not have that problem when I brought it in, after spending 5800 on my transmission and 2 weeks of waiting as well as having what sounds like a new issue I would not bring my car back.

I am satisfied so far with the outcome, although it took 2 weeks to address additional issues that required a couple of returns. The staff were committed to finding the issue before returning it the final time, and I appreciated that.

Justin at Mr. Transmission on Upper James Street is honest, professional, and truly stands behind his work. When my engine light came back on just 10 days after the repair—even though I had driven the car only twice—he asked me to bring it in right away. He quickly determined that the brand-new replacement part was defective, replaced it, and charged me nothing for the additional diagnosis or repair. That kind of honesty and commitment to customer service is rare today. I highly recommend Justin and his team.

A very good experience. Free diagnostic, free road test, and free honest information. I was informed the issue with my car is not the transmission but they are unable to fix the problem. I appreciate the honesty most of all.
