Why We Are a Core Supplier for 8AT Automatic Transmission in China— Reliable Manufacturing Precision Components · Efficient Delivery

As the Chinese automotive industry advances toward higher performance and fuel efficiency, the 8-speed automatic transmission (8AT) has become a standard in mid-to-high-end vehicles.
Meeting the stringent demands of 8AT requires high-precision, durable, and consistent components.

At Wenling Yuxiang Machinery Parts Co., Ltd., we leverage over a decade of experience in precision transmission system components to become a trusted core supplier for multiple domestic 8AT transmission manufacturers.

1. Over a Decade of Focus on Transmission Components

Yuxiang specializes in precision stamping, machined, and assembly parts for automatic transmissions, offering customers full support for their transmission production chain:

Stamping Parts: clutch housings, pump covers, support plates, locating rings

Machined Parts: flanges, plates, pistons, oil channel covers

Assembly Components: high-precision composite parts integrating stamping, machining, and welding

Our solutions serve AT, CVT, and DCT transmission systems, ensuring compatibility with diverse automotive platforms.

2. IATF 16949 Certified Quality Management System

Becoming a core 8AT supplier requires strict quality standards. Yuxiang Machinery has achieved IATF 16949 certification, implementing PPAP, APQP, SPC, and MSA across production processes.

From raw material intake, die production, stamping, CNC machining, heat treatment, surface coating, to final inspection, every step is data-monitored and fully traceable.
This allows us to consistently achieve ±0.005mm dimensional accuracy, meeting the tight tolerances of complex 8AT transmission structures.

3. Automated and Digital Production Capabilities

To satisfy high consistency requirements, Yuxiang has upgraded to fully automated and intelligent production lines:

Multi-station high-speed stamping lines with automated feeding and inline inspection

Robotic CNC machining units ensuring stable dimensions and high efficiency

Vision-based inline inspection systems for zero-defect delivery

MES digital management to monitor production progress and quality in real time

Each line achieves a cycle time of 15–20 seconds per unit, enabling fast delivery for large-scale production.

4. Deep Collaboration with OEMs

Yuxiang is more than a manufacturer — we are a technical partner.
We collaborate with leading domestic transmission OEMs (8AT, 9AT, and hybrid DHT systems) from the early design phase, optimizing manufacturability and process efficiency.

By leveraging CAE simulations and die flow analysis, we reduce mold modifications and accelerate product launch timelines. This co-development capability is a key reason why we are a core supplier.

5. Quality and Trust: Long-Term Partnership

With consistent delivery, cost-effective production, and reliable quality, Yuxiang Machinery is the preferred supplier for multiple domestic and international transmission manufacturers.

We understand that even minor deviations in 8AT components can affect the entire transmission system. That is why we adhere to a "zero defect" philosophy, ensuring every part meets stringent OEM standards.

6. Looking Forward

As China continues its push toward new energy vehicles and hybrid systems, transmission components are evolving toward lightweight and integrated designs.

Yuxiang Machinery will continue investing in material optimization, automated manufacturing, and precision assembly, supporting the next generation of DHT hybrid, 10AT, and electric drive reduction systems.

With reliable manufacturing capabilities, we are not only an 8AT supplier but also a committed partner in advancing China's high-end powertrain industry.
