At Mister Transmission, we have state of the art diagnostic technology to determine exactly what is going on with your vehicle, and the most cost-effective solution to repair it.

I was having a horrible time trying to figure out what was wrong with my car. It was jerking when I tried accelerating, and after going to a few other mechanics who couldn’t find the issue (I had thought it was a transmission issue), I ended up booking an appointment with the lovely team here at the Belleville location. They figured out it was an air intake boot that had broken, and since fixing it, the car now drives like a dream! A year of trying to figure out what was wrong with the car, and many sleepless nights, I can now rest easy knowing it drives like it’s supposed to. I can’t thank the team here enough, you guys rock! Not only are they the nicest people you can meet, they are trustworthy and extremely helpful and knowledgeable. As a woman who knows literally nothing about cars except the absolute basics, they had explained what they did to fix the issue, and how and why it made my car drive so roughly. I will definitely be coming back if my car needs any work done in the future. Thank you!

On Saturday, a mechanic shop quoted me $869 for the repairs. A friend on mine suggested I contact Mr. Transmission. I called and spoke to Barry who is the owner and he asked me to bring the car today. His machinic found the exact problem and fixed it. The cost? $83. A very honest mechanic shop in Belleville. I recommend Mr. Transmission to anyone who needs an honest mechanic. Thank you Barry.

Were able to look at my transmission and take my vehicle for a drive shortly after I called. The issue didn't flare and yet they didn't charged me anything for their time. This was much appreciated and they have my business for next time. Thanks team mister transmission.

Patricia Nauta
I can't say enough about this place. I went with anxiety about a possible malfunctioning car and they took it for a test drive, put it on the hoist, pumped up my tires, did some measurements and filled some fluids and best of all reassured me that I was safe and good to go!!! When was the last time that happened to you?? Barry and Kia were both amazing and when I do have legit problems with the car they will be the ones I trust and return to.
