Overview
Shengrui Transmission is an automotive transmission manufacturer based in Weifang, Shandong Province, China. Founded in 2003, the company is a relatively recent entrant to the automotive powertrain industry and has focused primarily on the research, development, and production of automatic transmissions, while also being associated with manual-transmission manufacturing. Its best-known program is an eight-speed automatic transmission developed with engineering support from the British consultancy Ricardo plc. Shengrui's development path illustrates the technical and commercial challenges faced by Chinese transmission manufacturers seeking to build advanced automatic gearboxes. In 2009, the company contracted Ricardo to design an eight-speed automatic transmission. The initial engineering agreement was reportedly valued at £1 million. After the transmission entered production, Shengrui encountered calibration and drivability problems and lacked sufficient in-house experience to resolve them independently. It therefore engaged Ricardo for a further support program, reportedly involving another £1 million payment, aimed mainly at solving those issues. The project took several years to reach a vehicle customer. Almost five years after the initial development work began, Jiangling Motors Corporation, commonly known as JMC, selected the Shengrui eight-speed automatic transmission for the X-7 sport-utility vehicle. The X-7 was offered with an automatic transmission, an unusual configuration for a Chinese vehicle at the time described by the available reference material. Transmission-related difficulties contributed to a production-start delay of more than six months, demonstrating the importance of calibration, drivability refinement, validation, and supplier integration in bringing a new gearbox into series production. The X-7 subsequently became a significant application for the eight-speed unit. Reference material reported monthly sales of more than 6,000 vehicles in December 2015 and described the transmission as being used in the vehicle's automatic-only configuration. This gave Shengrui a visible production application for an advanced automatic gearbox and helped establish the company as a domestic Chinese participant in a market historically dominated by larger international transmission suppliers. Shengrui is also described as a subsidiary of Shandong Wei Cai Diesel Engine Manufacturer and as a parts supplier to that business. Beyond the eight-speed automatic program, publicly available material identifies the company's broader business as automotive transmission research, development, and manufacturing. Detailed information about its current product portfolio, production capacity, ownership structure, executive team, international sales, financial performance, and present operating status is not established by the supplied references.
History
Shengrui Transmission was established in 2003 in Weifang, Shandong Province, as a Chinese automotive transmission manufacturer. The company is described in the available reference material as a subsidiary of Shandong Wei Cai Diesel Engine Manufacturer and as a supplier of parts to that business. Its principal area of activity has been automotive transmission engineering and production, with particular emphasis on automatic transmissions. A major stage in Shengrui's development began in 2009, when it hired Ricardo plc, a British engineering and technology consultancy, to design an eight-speed automatic transmission. The reported value of the initial contract was £1 million. The project represented an effort by a comparatively young Chinese transmission manufacturer to develop a complex gearbox suitable for series-production vehicles rather than relying solely on established foreign designs. Although the eight-speed transmission reached production, the program encountered technical difficulties. The available account identifies calibration and drivability as the main problem areas. Shengrui did not yet have enough internal experience to address those issues without outside assistance, so it contracted Ricardo again for additional development and troubleshooting support. The second engagement was also reportedly worth £1 million. The combined development and refinement process extended over several years. After almost five years, the transmission obtained its first identified vehicle application with Jiangling Motors Corporation. JMC used the Shengrui eight-speed automatic in the X-7 sport-utility vehicle. The vehicle was presented as an automatic-only model, an unusual market configuration in China at the time. Difficulties with the transmission contributed to a production-start delay of over six months, reflecting the challenges of validating a new gearbox in a complete vehicle and achieving acceptable shift behavior under production conditions. The X-7 later provided a substantial production outlet for the transmission. The available reference material reported monthly X-7 sales of more than 6,000 units as of December 2015 and indicated that the Shengrui eight-speed automatic was being used in those vehicles. This application gave Shengrui a commercial reference point for its technology and demonstrated that the company had moved beyond prototype development into series supply. Publicly available information supplied for this dossier does not establish a complete account of Shengrui's later history. There is insufficient verified material to describe subsequent vehicle programs, new transmission generations, manufacturing expansion, ownership changes, financial performance, executive appointments, or current operating status. The company's documented historical profile therefore centers on its founding, its Ricardo-supported eight-speed automatic-transmission program, and the gearbox's adoption by JMC for the X-7.

Automatic transmission
Eight-speed automatic transmission
Shengrui's best-documented product is an eight-speed automatic transmission developed with Ricardo plc. The program involved initial design work followed by additional engineering support for calibration and drivability problems encountered during production. Jiangling Motors Corporation became the first identified vehicle customer, using the gearbox in the X-7 sport-utility vehicle. The transmission's development and vehicle integration took several years and contributed to a production-start delay of more than six months for the X-7.
