As the founder of Trans-Dapt Performance (now Trans-Dapt Performance Products), Willie began selling transmission adapters out of his garage, before the company went from a two-man operation to being a key player in the performance industry, offering many quality products. Willie was also active during the formative years of SEMA. He had an appreciation for the importance of a trade group to protect the industry in cases of governmental overregulation, and was instrumental in the Association’s influence in legislative affairs.
