Sonnax & Rostra Powertrain Controls: Two Brands, One Company

Sonnax Transmission Company is excited to announce a recent reorganization, integrating Rostra Powertrain Controls into the company’s Vermont- and North Carolina-based Sonnax operations. This concludes several years of internal moves aligning teams and resources to better serve the transmission aftermarket. Both the Sonnax and Rostra brands have been part of Marmon Holdings, Inc. since 2018, with Steve Boyer leading both teams as President since 2020.

“Through this integration, Rostra and Sonnax will become a single, transmission-focused organization,” said Boyer. “This new structure will synchronize our product development efforts, reduce time to market of new products and allow us to make improvements in quality and delivery to our shared customers.”

Boyer said several internal promotions were made to support the alignment of both brands under Sonnax Transmission Company:

Maura Stafford is appointed company Vice President of Transmission Products. Stafford and her team manage product groups focused on hydraulic and electronic transmission components, solenoids and remanufactured valve bodies.

Steve Jaussaud continues as company Vice President of Product Line Management, guiding development of torque converter, high performance, driveline and mechanical transmission components. Jaussaud also manages the torque converter product line, a responsibility he assumed in late 2020.

Beth Houder is appointed company Vice President of Marketing & Communications, leading marketing efforts and the continued development of both brands in the aftermarket industry.

Mark Kaplan serves as company Vice President of Sales, assuming sales management for Sonnax and Rostra. He is joined by Seth Baldasaro, Director of Strategic Accounts, and Tony Diorio, National Accounts Manager.

Introducing the Sonnax Tool Shop

Through customer calls, emails, surveys, and conversations at industry events, we heard you loud and clear: some Sonnax tools have been hard to get, and the prices were too high. We brought your concerns to our distributor partners, and worked together to build the Sonnax Tool Shop.

The goal of this program is simple: help you get the tools you want, when you want them, at a fair price. The Sonnax Tool Shop includes 70+ popular F-tool  and vacuum testing products with new, lower MSRPs and greater distribution at local branches and regional distribution centers.

“At the Sonnax Tool Shop, the price you see is the price you pay,” says Mark Kaplan, Sonnax Vice President of Sales. “We’re grateful for the support of our network of distributors in offering MSRP-or-better prices and 1-2 day delivery on this selection of tools to all customers in the U.S. and Canada.”  

A key benefit for rebuilders: If a Tool Shop part or kit isn’t readily available from your regular local branch, you can call other Sonnax distributors without worrying that you’ll have to pay more.

Check out the complete list of included tools and MSRPs here: Sonnax Tool Shop

Introducing the Sonnax Zip Valve™

Need or prefer a drop-in repair for common shift problems? 

Introducing Zip Valve™ products – a new brand covering the hundreds of drop-in valves and Zip Kits rebuilders have trusted for years to overcome chronic transmission problems. These easy-to-install components deliver quality and performance that can’t be beat thanks to upgraded Sonnax design features, improved materials and precision manufacturing. 

More than 350 different products covering 200-plus transmissions are available, and it’s easy to identify these parts anywhere on the Sonnax website by the new, drop-in “ZIP” logo that accompanies each one. Just like you can narrow down search results by unit or part type, choosing to display only Zip Valves is now another option for quickly finding just the right repair. 

“At Sonnax, we strive to have the best selection of highest-quality solutions available for our customers.” says Sonnax President Steve Boyer. “When you’ve got a build on your bench, it’s our job to provide you with a wide range of options you can trust.”

COVID-19 Operations Update

It is our sincere hope that you and your families remain safe and in good health. The unprecedented humanitarian and economic crisis we find ourselves in is like nothing we could have ever imagined. 

At Sonnax, it is our goal to serve you in these uncertain times in a safe and responsible manner. We are working every day with our supplier and distributor partners to continue providing the parts and product support you need. 

Safety has and continues to be our first priority, and we have instituted additional hygiene protocols and safety measures to keep our employees as safe as possible. Our IT infrastructure has been optimized to enable employees to work from home when possible, while minimizing impact on operations and production.

Additionally, we have decided to temporarily suspend operations in our facilities on April 13, 24 and 27.  

We remain committed to the idea that this crisis will be temporary, and that we will need full capacity to meet customer needs as the market recovers. As we continue to navigate our way through this crisis, we are grateful for your support and partnership in the market we serve.
