The automotive aftermarket has long been familiar with Torrington bearings. Although most people know that Torrington is a company that manufactures these bearings, the term “Torrington bearing” has become synonymous with needle roller thrust bearings. “Torrington bearing” has become a generic term describing a type of bearing as much as it indicates a manufacturer who produces those bearings.

The Torrington Company was established in 1898 in Torrington, Conn. It was an independent company until an acquisition by Ingersoll Rand Corp. in 1968. In 2003, Torrington Bearing was sold to the Timken Company, which produced Torrington brand bearings until 2009. In 2009, JTEKT Corporation of Japan acquired the Torrington bearing line – including the manufacturing plants and tech center along with 3,400 employees – from Timken. Torrington became part of the JTEKT’s Koyo Bearings.

Since 2013, these products formerly known as Torrington bearings were marketed solely under the Koyo brand name.

In April and November 2022, JTEKT North America provided notification regarding the unification of the Koyo bearing brand to the JTEKT brand. Be aware there is no change in ownership associated with the name change. This change is simply a consolidation of the Koyo bearing brand to the globally recognized JTEKT brand.

JTEKT Bearings — changing its name from Koyo Bearings — is the Torrington Legacy, and you can count on Sonnax providing you with the same great OE quality you've always received under the Torrington brand... only the name has now changed to JTEKT.

Every year, Transmission Digest accepts nominations for the top 10 products and tools in the powertrain aftermarket.

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.

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.

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.”

Due to the coronavirus outbreak, non-essential businesses in Vermont have been ordered to shut down.

In addition, Sonnax has provided extra cleaning/sanitizing protocols, providing appropriate Personal Protective Equipment and extra hand sanitizing products that are conveniently located.

• Washing hands often with soap and water for at least 20 seconds.
• Avoiding touching your eyes, nose and mouth with unwashed hands.
• Avoiding close contact with people who are sick.
• Covering a cough or sneeze with a tissue, then throwing the tissue in the trash.
