Very friendly staff, knowledgeable and very professional. My vehicle had to have the transmission pan replaced because the filter is part of the pan. They stocked the pan and it wasn’t too bad of a price either. Dropped off the vehicle for 8 and it was done shortly before lunch. Highly recommend and would definitely return for my next service.

Shawn Harriman
I was in an extreme pinch. It was a Thursday and I was leaving on a long road trip Sunday, and thought my transmission wasn’t shifting properly. They couldn’t get me in Thursday afternoon so the got me in for a free road test and diagnostic early Friday. Transmission was great but had a really bad wheel bearing. They said they may get me in at the end of the day, but it wasn’t a guarantee. I didn’t realize they closed at 3 on Fridays and called just before 3 to see if I was getting in. The receptionist said no dice, and I hung up. Before I could call another garage she called back and said they’d squeeze me in. They worked on it til 5, when it was done! Jo-el was so friendly and went more than an extra mile for me, and made our trip a success! Thanks so much to your team!!!

had a good experience at Mr. Transmission. The staff were professional and took the time to clearly explain what was wrong with my car. They didn’t rush anything and made sure I understood the repair before starting. The service was done on time, and my car is running much smoother now. Overall, a reliable place if you’re dealing with transmission issues.
