Customer Reviews

I am very pleased with...

Bill Martin

I am very pleased with the service provided at Mr. Transmission. We had our transmission break on our 2019 Ford Explorer, and the dealer quoted us 10-12K! I called Mr. Transmission, and they were able to rebuild it for half of the price. Lee was very informative, and kept me up to date with the progress. I'd recommend Me.Transmission to anyone who would like the save money at the dealer, and get their transmission rebuilt.

Kael MacNeil

Professional and thorough service. Provided me with a full transmission rebuild after a critical failure with any and all issues covered under a 20,000km warranty. Gave me an excellent deal on cost and went the extra mile finishing up some small projects I was working on under the car at no added cost.

David

I can not recommend these guys enough. A few years ago these guys fixed my front dif for half of anyone else because they were willing to fix it rather then replace it and it's still going strong. Many km later my transmission started having rough shifts and other shops told me my transmission was not serviceable. Mr transmission saved me again and was able to do a transmission service and get my truck driving like new again!

Nicole W

I brought my car in to have the clutch replaced back in March. I was in a rush to get my car in somewhere, and after having been quoted $5k by the dealership, the staff at Mister Transmission accommodated me within the hour and did the service for $1k less than the dealership. Later, there was an issue with the battery when the car was returned home and they looked at it for me at no cost. They even called a week or so later to make sure that the car was running okay.All around great service, great prices, and friendly staff. Thanks a bunch!

Denise is such a blessing. We had some transmission troubles with our minivan. Aside the impeccable service, she also offered some support to my family which went a long way. I loved my experience here and I'm sure everyone else has also.
