Core Technical Advantages
1. Compact and Lightweight Architecture
The 7DCT300s achieves its compact dimensions through innovative design and advanced materials. At 76 kg, this automatic transmission is among the lightest in its torque class, contributing to improved vehicle fuel economy and reduced emissions. The compact packaging also provides vehicle manufacturers with greater freedom in powertrain layout and vehicle architecture design.
2. Wet Dual-Clutch Module for Durability and Smoothness
The wet dual-clutch design employs multi-disc clutches operating in an oil bath, delivering exceptional heat dissipation and wear resistance. This architecture makes the 7DCT300s a durable and reliable automatic transmission for daily driving conditions. The wet clutch system ensures smooth launches, consistent performance across temperature ranges, and extended service life – all critical attributes for a modern automatic transmission used in high-volume vehicle programmes.
3. Electro-Hydraulic Actuation for Precision Control
The 7DCT300s utilizes an advanced electro-hydraulic actuation system that provides rapid, precise control of clutch engagement and gear selection. This system enables shift times measured in milliseconds, delivering the responsive driving experience that consumers expect from a premium automatic transmission.
The electro-hydraulic design also supports integration with hybrid systems, making the 7DCT300s a versatile automatic transmission for both conventional and electrified vehicle programmes.
4. Electro-Hydraulic Parking Mechanism
The transmission features an electro-hydraulic parking mechanism, offering enhanced functionality and integration capabilities. This advanced parking system enables features such as automatic park engagement and seamless integration with vehicle electronic systems, further enhancing the value proposition of this automatic transmission.
5. Comprehensive Hybrid Support
The 7DCT300s supports multiple hybrid vehicle architectures:
- BSG (Belt-Start Generator) – Mild hybrid integration
- P2 hybrid – Motor positioned between engine and transmission
- e-AD (Electric Axle Drive) – Supporting through-the-road hybrid configurations
This flexibility positions the 7DCT300s as a future-ready automatic transmission that can accommodate various electrification strategies across different vehicle programmes.
Application and Market Penetration
Selected by Leading Chinese Vehicle Manufacturers
The 7DCT300s has been adopted by prominent Chinese automotive manufacturers as a preferred automatic transmission for their vehicle lines equipped with 1.5T engines. The transmission has already secured multiple vehicle programme awards from major Chinese vehicle groups, underscoring its technical competitiveness and market acceptance.
Ideal for 1.5T Powertrains
With its 200–300 N·m torque capacity, the 7DCT300s is perfectly matched to 1.5T turbocharged petrol engines – one of the most popular powertrain configurations in the global automotive market. This automatic transmission delivers the optimal balance of performance, efficiency, and cost for compact and mid-size vehicles.
SUV Applications
The 7DCT300s is particularly well-suited for SUV applications, having been adopted for use in models that include the HAVAL SUV lineup. The transmission's compact dimensions, lightweight construction, and robust torque capacity make it an ideal automatic transmission for SUVs, where durability and efficiency are paramount.
SC-industry, as a dedicated transmission supplier, can provide this proven automatic transmission for SUV programmes with the reliable supply chain management support that ensures consistent production delivery.
