Remanufactured 7DCT440 Dual Clutch Transmission Assembly for Hongqi H9 2.0T 2020-2024 1701020-A5K-C01 7 Speed DCT Gearbox Factory Reman Trans Replacement Gearbox for Auto Repair Shop

This remanufactured 7DCT440 7-speed wet dual clutch transmission assembly is factory rebuilt exclusively for Hongqi H9 2.0T models. Our factory fully disassembles, cleans, inspects and reassembles each unit. Most wearing internal components are replaced with brand-new OEM parts to restore performance to original factory specification. Every finished gearbox goes through full bench dynamometer testing before shipment, to eliminate hidden failure risks. Suitable for direct replacement for failed original transmission for vehicle maintenance and overhaul projects.

1. Full disassembly, blast cleaning of housing, remove all sludge and wear debris.
2. Inspection of housing cracks, deformation and thread damage; defective housings will be rejected.
3. Replace vulnerable parts: clutch assembly, bearings, seals, piston, friction plates, solenoid valve with OEM-new spare parts.
4. Assemble strictly following FAW factory assembly torque and procedure standard.
5. Dynamometer bench test: simulate real road working condition, test shifting logic, pressure, leak check, temperature stability.
6. Oil leakage inspection and final visual quality check before packaging.

A: Yes, our remanufactured 7DCT440 7-speed wet DCT fully retains the factory-designed auto start-stop function for Hongqi H9 2.0T models from 2020 to 2024. We keep all matching sensors and solenoid components in original specifications during remanufacturing. However, you need to remind your end clients that after installation, professional diagnostic equipment must complete TCU coding and clutch adaptive learning. If the adaptation procedure is skipped, start-stop logic may not work normally even though the hardware is intact. Our engineering team can share the detailed operation guide with your workshop team remotely. We also suggest checking the vehicle battery health status, since weak battery is another common cause for disabled start-stop function, which is not related to transmission quality.

A: We have strict inspection criteria for incoming old core 7DCT440 gearboxes once you return cores for core deposit refund. We will reject cores with cracked or seriously deformed housing, broken internal shafts, burned clutch assembly caused by long-time overheating, severe water damage or rust inside the gearbox. Cores with missing major internal components such as valve body, input shaft or clutch pack will also be refused. Before you ship back old cores, our sales team can send you a core checking checklist, so your team can pre-inspect cores locally to avoid extra return freight loss. We will send full inspection photos and reports after we receive and examine each returned core.

A: Absolutely, mixed container loading is available for our wholesale buyers. You can combine 7DCT440 Hongqi H9 transmissions together with other remanufactured gearbox models we produce in one sea container. This solution is very helpful for auto parts distributors to diversify your product inventory without paying for multiple separate shipments. Our logistics department will calculate the weight and volume for all items, arrange proper fixing and separation inside the container to prevent collision damage during ocean transit. We will also combine all products into one set of commercial invoice, packing list and customs documents to simplify your import customs clearance process. Just send us your required product list, and we will work out the best loading plan for you.
