An automatic gearbox from TOSEN AUTO ensures smooth, efficient shifting without manual clutch operation. We engineer our systems for high performance, reliability, and fuel efficiency. Advanced technologies deliver seamless transitions under diverse driving conditions. Whether equipping passenger vehicles or commercial fleets, our transmissions provide optimal power transfer. They enhance both driving comfort and overall vehicle performance. As a high-volume B2B supplier, we achieve an annual sales volume exceeding 12,000 gearboxes globally. We proudly support distributors, wholesalers, and transmission repair centers with reliable aftermarket options.
Procuring the right replacement assembly requires a precise match to the manufacturer's transmission family. We structure our catalog to simplify the search for transmission repair shops and distributors. Our team groups assemblies by their specific design configurations and manufacturer codes.
| Gearbox Family / Series | Application Type | Key Features & Technologies |
| Mercedes-Benz CVT & DSG Series | Premium Passenger Cars | Continuous variable transmission, integrated electronic control modules |
| Heavy-Duty RWD Assemblies | SUVs & Commercial Fleets | Robust torque converters, enhanced load endurance |
| Compact FWD Multi-Speed | Urban Passenger Vehicles | Compact casing design, optimized fuel efficiency and shifting speeds |
We offer sought-after solutions like the 722.8 TCM CVT and various dual-clutch DSG systems. These premium European passenger car transmissions act as direct-fit replacements. They preserve the original driving dynamics and electronics of the vehicle. Furthermore, they ensure full software compatibility with factory control units.
Our product line covers light commercial delivery fleets, daily passenger cars, and rugged SUVs. Designed for robust power transfer, these assemblies withstand demanding load cycles. They easily handle heavy stop-and-go city traffic without sacrificing reliability or shifting comfort.
Sourcing high-quality individual components is vital for specialized rebuilders and distributors. TOSEN AUTO offers a dual-track inventory strategy to meet these exact needs. We supply precision-engineered individual parts alongside fully integrated overhaul kits. This approach saves valuable lead time and reduces overall sourcing costs.
We supply high-precision electronic and electro-hydraulic units, including the 722.8 TCM. Each module and solenoid valve undergoes rigorous calibration and electrical testing. This guarantees precise pressure regulation and accurate shift timing. It also ensures seamless communication with the main vehicle ECU.
The physical core of any transmission relies on high-tensile alloy housings, precision-ground gear shafts, and durable synchronizer rings. We manufacture these components with strict dimensional tolerance controls. This prevents internal wear, eliminates unwanted vibrations, and blocks fluid leaks.
Our complete rebuild kits simplify ordering by bundling all necessary friction plates, steel plates, gaskets, seals, and solenoids. These packages correspond directly to specific gearbox codes. Purchasing our bundled kits avoids compatibility errors. They also significantly streamline rebuild workflows in high-volume repair shops.
Sourcing drivetrain parts should never involve guesswork. TOSEN AUTO provides B2B buyers with access to high-fidelity exploded schematic views and precise parts maps. By verifying original equipment (OE) numbers against our diagrams, your team can confirm component fitment before placing bulk orders. If you need assistance matching an assembly or internal component, simply contact our technical sales team. We are ready to provide direct catalog support and verification.
