Automatic Transmission Design, Inc.

Been haven my cars trucks look at here for over 20 years now. Great work an trusted shop. Thanks.

Guys are brilliant at diagnosing issues, and charging a fair price. Would recommend them 100%!

I took my 2000 Chevy Astro Van in for a transmission rebuild, I got back a week later and it shifts amazing, they were honest from beginning to end. My engine light came on shortly after which I knew why, so when I took it back to see what they would say, they gave me the right answer. Great job guys.

Honest and great work. Was told by another shop I needed a complete new transfer case. Brought it ATD to find out it was the encoder motor. They saved me $1500.

Had them remove, rebuild, and reinstall a TH400 in a C3 corvette last summer. No problems with it since (around two thousand miles) and the minor upgrades to torque converter and other parts are definitely an improvement over stock. Scott was knowledgeable and helpful with selecting the right parts for the car. Cost and time were a little more than estimated, but not by much, in spite of the inconvenience of working on the C3. They damaged a deteriorated (original) oil line while reinstalling the trans and repaired it at no labor cost, even though it caused them considerable time and hassle. Props to them for that, since they were more than justified to charge for it, given the age of the part. The only minor complaint I had was that communication was a little lacking, but they did answer the phone whenever I called. Overall great work, I would highly recommend!
