Press Releases



Detroit, MI, March 19, 2017 – Superior Capital Partners, LLC, a Detroit-based private equity firm, announced today that it has sold the Powertrain Division of Rostra Precision Controls to The Marmon Group, a Berkshire Hathaway Company. Based in Laurinburg, NC, Rostra’s Powertrain Division is the leading provider of solenoids, sensors, wire harnesses and other electrical components utilized in the repair of transmissions. The Powertrain Division also manufactures components for heavy-duty transmission manufacturers.

Following the sale, Superior maintains ownership of Rostra’s Accessories business unit, a supplier of lighting products, obstacle sensing systems and other electronic accessories for light-duty vehicles as well as Vehicle Safety Manufacturing, the largest manufacturer of turn-signal switches for heavy duty and specialty vehicle applications in North America. VSM also supplies lighting products to the heavy-duty and specialty vehicle markets.

Over Superior’s ownership period, the Powertrain Division has broadened its product line of highly technical electrical products utilized for the repair of transmissions, expanded its distribution channels and established itself as the go-to brand in the transmission repair industry.

Mark Carroll, Superior’s Managing Partner, said, “When we acquired Rostra, we knew we were acquiring a business with strong technical capabilities, a great brand in its niche market and staying power. The Powertrain Division proved resilient through the economic downturn and has experienced strong growth. It will be enhanced by the significant reach and resources that will come from The Marmon Group. This sale is a fantastic outcome for Rostra’s employees and shareholders alike.”

Jim Pineau, Rostra’s CEO, commented: “We’re very pleased to have found the perfect home for the Powertrain Division. We’re also extremely excited about the future of Rostra Accessories and Vehicle Safety Manufacturing. We have the resources and focus to continue to grow both brands with industry leading products and world-class quality.”
