Transmission repair service near Vashon, WA

Recommends provided by Maddy's Automotive Service is the best transmission shop in town.. Tom Maddy has worked on all of my vehicles in the last ten years. He is a transmission specialist that is honest and fare on his pricing. He can fix anything under the hood; exhaust systems; breaks and do frontend alignments.

I drove to Firestone in Redmond to get our actively leaking radiator fixed. Firestone was unable to fix our car for 5 days. So I went next door to Autosys and they were able to fix the car in a more timely manner. Tyler at the desk frequently communicated the status of our Excursion with us. The price of labor and parts was reasonable and fair. And....I got a ride home from one of the workers since our car had to stay there. I will definitely go back!

Your customer service is wonderful. It's important that I feel I can trust who I take my car to & I trust ZahnTech. I'm glad I found you.

I found the staff to be Audi experts and enthusiasts. I really appreciate that they went above and beyond to fix the car correctly, and communicated with me each step of the way. would highly recommend!

Great customer service, excellent mechanic and the car drives like its brand new. I couldn't be happier with the experience and the end result.

Wonderful friendly service
