What Rostra Powertrain Controls does
Rostra Powertrain Controls is a manufacturer and distributor of OE and aftermarket transmission electronic components, organized as an integrated brand division of Sonnax Transmission Company, Inc., which is itself a wholly-owned subsidiary of Marmon Holdings (a Berkshire Hathaway company). Its product portfolio spans five core categories — solenoids (EPC, variable force/bleed, TCC lock-up, shift, linear control), sensors (input/output/turbine speed, MLPS/NSS, fluid temperature), pressure and clutch switches, internal and external wire harnesses and connector repair kits, and vacuum and electric modulators — along with an OEM/S Parts line positioned as authentic OE components direct from manufacturer supply chains.
The company supports passenger, commercial, and heavy-duty vehicle applications. Its catalog is stated to cover more than 95% of U.S. vehicles across 200+ transmission models from manufacturers including Aisin, Allison, Chrysler, Ford, GM, Honda/Acura, Jatco, Mazda, Nissan, Subaru, Toyota/Lexus, ZF and others, with named end-use presence in USPS, FedEx, UPS, Walmart, and Amazon fleets, airport ground support, refuse and snow-plow trucks, and OE applications such as Ford's supercharged Mustangs. Rostra's Laurinburg, NC facility holds IATF-16949:2016 and ISO-9001:2015 certifications.
Rostra monetizes through hardware sales of its component catalog via a multi-tier channel: an authorized distributor network (including Transtar, TCS, PDQ, and 20+ others) and major retail chains (AutoZone, NAPA Auto Parts) for the U.S. and international aftermarket, supplemented by direct B2B relationships with repair shops and fleet operators. Pricing is quote-based through distributors and is not publicly disclosed. In August 2021, Sonnax Transmission Company fully integrated Rostra into a single transmission-focused organization, and since 2018 both brands have operated under Marmon Holdings. The combined Sonnax/Rostra organization employs 200+ people across facilities in Bellows Falls, VT (Sonnax HQ), Laurinburg, NC (Rostra production), and Grand Rapids (engineering/R&D).

Products and services
- Solenoids Transmission control solenoids including EPC (Electronic Pressure Control), variable force, variable bleed, TCC lock-up, shift, and linear control solenoids. These regulate hydraulic pressure, control shift timing, and manage torque converter clutch engagement in automatic transmissions for repair shops, fleet operators, and OE manufacturers.
- Sensors Speed, position, and temperature sensors for transmission monitoring including input speed sensors (ISS), output speed sensors (OSS), vehicle speed sensors (VSS), turbine speed sensors, manual lever position sensors (MLPS/NSS), and fluid temperature sensors. Provide critical data for transmission control and diagnostics in light-duty, commercial, and heavy-duty vehicles.
- Switches Transmission pressure switches and clutch pressure switches that monitor hydraulic system conditions and provide feedback to the transmission control system for proper gear engagement and shift quality in automatic transmissions.
- Wire Harnesses & Connectors Internal and external wire harnesses, connector repair kits, and pigtail assemblies that provide electrical connections between transmission sensors, solenoids, and the vehicle's control systems. Used by repair shops and fleet maintenance operations.
- Modulators Vacuum and electric modulators that control shift feel and timing by regulating hydraulic line pressure based on engine load and vehicle speed. Includes adjustable, electric, and various vacuum-operated types for transmission applications.
- OEM/S Parts Authentic Original Equipment Manufacturer/Supplied parts direct from OEM supply chains. Includes solenoids, control modules, switches, and sensors that are identical to factory-installed components, providing OE design and manufacturing quality for OE manufacturers, repair shops, and fleet operators.
- Solenoid Control Modules Electronic control modules that manage solenoid operation in various transmissions, including units for Chrysler (40TE, 41TE, 45RFE, 545RFE, 65RFE, 66RFE, 68RFE, 62TE) and other applications. Address pressure and shift complaints when properly diagnosed.
- 13 OEM/S Solenoids & Modules Expansion Product line expansion consisting of 13 OEM/S solenoids and modules secured through an agreement to succeed BorgWarner as the distributor of Solero Technologies OE solenoids. These 4- and 6-speed OEM parts were previously marketed under the BorgWarner brand and are now sold under the Rostra brand.
