Mike LeFebvre
Short and sweet. Had a Trans done in Pickering. Had a problem with seal leakage. Returned to Pickering location and no longer there. Drove to Mr Trans on Westney 195. Explained my problem. Steven the manager spoke to tech Tom and gave me a solution. Tom dismantled complete Trans. Found some serious flaws and proceeded to remedy them. Their work ethic customer service is top notch. Dealing with these guys is both comforting and educational. I highly recommend this specific shop for all transmission work bar none. Thanks again Steven and Tom. .

Professional place, good service. Had my transmission rebuilt and back to me in the time they promised and at the price they quoted no surprises. It's hard when transmission is so expensive but at least they got financing set up and helped me with a rental. Don't want to ever go through that agin but I would recommend.

I brought in my 2019 Chevy Equinox Diesel. I am giving it 5 stars after careful observation by driving the full kilometre limit of my warranty. I paid in full through a bank draft after a full rebuild consisting of the torque converter and a replacement of the valve body along with some solenoid sensors were done. Gamble paid off. However, I must indicate no repair work will fully restore a vehicle to its original state. I am thanking them with all my heart. Not a friend, nor family, just a stranger. Mister is an understatement here, they are Doctors. Carry on!

These guys are amazing. My regular mechanic doesnt do transmissions so he sent my car to a transmission shop he deals with and they said my transmission need to be replaced to the tune of $4000. I found these guys on line, they checked it for free and guess what, fixed it, works perfect for $786. Thank you Mister Transmission.

I was referred there by my friend who works for Peel Regional Police and he told me that's where they fix their cars. Great service and a good job. They rebuilt my 2017 Rogue transmission after other places told me they couldn't do it and dealer wanted crazy money. These guys saved me money and it’s been 3 weeks and it works like when it was new. I will recommend Mister Transmission.
