Hi I had my 1966 Chevelle Malibu SS in at Mister Transmission Sarnia to have the transmission worked on last year. Mike in the back shop worked on my car (pride and joy). He did the repairs that was needed done and a few extra things done without request. The car ran like a dream when I got it back. The cost was lower then they said it would be. I'm very fussy on who works on my car. The owner (manager) was awesome to deal with. Then this week 04 July 2025 I needed a shift cable repaired as I was headed out with my car . I went to the shop and they were over loaded with work. Mike made time to get my car fixed so I could use it on the weekend. They went the extra mile to get my car fixed and again I could not complain about the cost to repair the cable. I fully recommend them and the people that work there are outstanding. A special thanks to Mike who worked on my baby(my car) thanks so much guys. They are my go to shop with my Classic car and all my vehicles.
