Daniel, a business owner, transmission rebuilder, automotive technician, and entrepreneur, was raised in Montana, Wyoming, New Mexico, and California. He kick-started his career in auto repair and transmission rebuilding at Wyoming Technical Institute in 1986. He began his journey at AA Transmission before his career took him to Central California where he honed his skills on a vast range of vehicles. His entrepreneurial spirit led him to establish Accel Transmissions and later purchase Performance Transmissions, another local business with a rich 25-year history. When the opportunity to buy AA Transmissions - the very place where he started - presented itself, Daniel, alongside his wife Tanya, seized it.
Daniel's philosophy centers on providing top-notch service through continuous learning and collaboration with other downtown business owners. His goal is to offer quality, precision, and competent repairs via honest and diligent business practices, ensuring customers and their families are back on the road safely.

Tanya is an Eastern Montana native from Sidney and Havre, MT. She attended Dawson Community College and Upper Iowa University and holds a BS degree in Human Services with a minor in Public Administration. She gained further experience and training through a career in Public Health in Sidney and Billings. In 2008, she left her career to join her husband Daniel in purchasing AA Transmissions and today greatly enjoys working alongside him to accomplish their goals as a couple. Tanya functions as the Office Manager and Bookkeeper for the business. Instead of seeking to promote and encourage community health, she now seeks to help her husband and staff put satisfied customers back in their healthy vehicles.

Our Testimonials
Thanks for getting my vehicle driving again! I called all over billings for quotes on transmission work and you guys were the best and honest price I could find! And to get the call the work on my vehicle was all done and I got my vehicle back in 3 days! I was amazed you guys did an outstanding job on my vehicle which is running like new! Thanks again!
Would absolutely recommend this place for anything transmission related. Very pro-veteran, honest, and reasonable. Was able to get my Jeep in the same day of it breaking down and these guys worked diligently to get it back on the road. Joe was great to work with, honesty about servicing for my automatic transmission rebuild and pricing was upfront and straight forward through him. Even was able to get an insanely competitive price for the repair that I wouldn't have been able to get anywhere else in town. Absolutely zero complaints and deserves the five stars. Thanks again guys!
Thank you so much for your wonderful car care! We were thrilled with your expertise, professionalism, and fairness. It was so "different" in your idndustry in receiving honesty, a smile, trust, an explanation, and overall excedance of expectations in a positive way...you guys are awesome....
My transmission went out on my car, I ended up getting rid of car instead. I really appreciated the honesty, the thorough explanation and very reasonable evaluation charge. They have earned my trust and will be my go to mechanic for any transmission work or maintenance in the future. Thank you for your honesty even though it cost you a repair.
I cant say enough great things about this shop! We were home on an emergency leave situation thought we were gonna lose a transmission so pulled into the first place we came up on! Little did we know the first thing he would say is it isnt your transmisison. He pushed us to the front of the workload and worked night and day to have us back out on time, put it to the test 2200 miles later we were in our driveway good as new! Sometimes it is good to have things break when you are home! We have since moved that vehicle to Hawaii and put about 3000 more miles on it and not a single issue!
Thank you very much for all you did when the transmission went out on our car last month - the car worked fine getting us back on Friday the 24th. You really went out of your way to help us find a place to stay, taking us there (in 2 Trips!) and driving the finished car to us at the hotel! We'll always think of you both and Montana as a "good" place to break down and how kind you were.
I was traveling thru Billings this summer and my car broke down with me and my 2 kids. It wouldn't move and the first place I called quoted me for a new transmission... scary! Then I talked to Dan at AA and he had my car towed in and check out and I DIDN"T need a new transmission! I wasn't planning on car repairs but at least I found a good mechanic and it didn't cost me a fortune. Thanks to Dan you your team! Hope I never break down in Billings again but if I do I know where to go!!!! 🙂
I needed my brakes repaired and AA Transmission got me in the next day. Joe communicated well with me on the cost, and he even saved me $140 in service fees. AA Transmission is the best shop in Billings, with incredibly fair prices!
