Spirit Award Recipient, 2019

Led by owner Karen Mason, United Transmission Exchange of San Bernardino remanufactures Allison automatic transmissions for heavy duty on highway vehicles, serving as the largest facility of its kind in California with over three acres and a 42,000 square foot building. Karen, along with her husband Tommy Mason, founded the company and along with a team of dedicated employees began to build up the struggling enterprise led by Tommy?s inspirational team approach. When Tommy?s health began to fail, Karen found herself in the chief executive?s role. She possessed no business management or relevant industry experience and ascended into a leadership position in the male-dominated heavy-duty trucks and transmission arena. Today the company employs nearly 30 skilled staff members and is the largest independent transmission remanufacturing facility in California.
