United Transmission Exchange • Established in 1975

United Transmission Exchange started as a small family business in 1975.  It has grown into the largest independent remanufacturing facility in California due mainly to our team approach to customer support and excellent product quality.

Many of our employees have been here since the company started and we employ the best in the business.  We believe that our company must be a safe, supportive and collaborative team effort because we spend more time here working than any other place beside our homes.

Our unique approach comes from Tommy Mason, a pro-bowl running back who was the number one draft pick in the NFL.  Tommy owned United Transmission Exchange and he believed that teams won because they supported each other no matter what the challenge.  Like Tommy, we all believe that our customers are on our team.  We take care of our customers because they take care of us.

Tommy passed away in January 2015 and we miss him every day.  He was an inspiration to everyone and our company is a special place because of him.

United Transmission Exchange has the largest selection of parts so we can services all of your Allison transmissions.
