I highly recommend this place to anyone who is looking for honest dependable mechanics. We called and made an appointment, they got us in within a few days and we got our vehicle back the same day. They were honest about everything and they did not charge a whole lot.

I have taken my car to multiple places who couldn’t figure out what was wrong with it. The guys at Middletown knew exactly what was wrong and were able to fix everything at a reasonable price. Hanna was kind enough give me a ride back to my house while waiting which only took a day to fix. I won’t take my car anywhere else! Highly recommend this place.

Middletown Transmission did a great job rebuilding the transmission in my 03 Silverado & taking care of a emissions issue, they kept me informed of the repair, were extremely helpful & friendly in person & on the phone. If you need your vehicle repaired, Nick & Hanna can definitely get you back on the road! Awesome job, I plan to use them again & would highly recommend Middletown Transmission to anyone!

Honest, good pricing, quality craftsmanship, and very professional. Its hard to believe that an auto repair business would have all of these qualities but they do. We will be taking our vehicles here from now on.

Needed some random upkeep done and I’m useless when it comes to cars. They explained what should be done to keep my car in good standing and gave me the option of what I wanted to do. It took no time and was less than I thought since I’ve never had maintenance done in the 2 years I’ve had it 🤦🏼‍♀️ Will definitely recommend and come back!
