Transmission & Drivetrain Parts
Clutch · CV axles · Gearbox internals · Bearings
XYQC exports clutch kits, CV axles, drive shafts, gearbox bearings, synchroniser rings, differential parts and complete remanufactured transmissions for Chinese-brand vehicles. Both manual and DCT applications are covered, and the CVT units used by Geely and Chery are supported with belt, pulley and valve body components. Fitment is confirmed against the OEM number or the VIN before a price is issued.
What we supply
Drivetrain is the category where aftermarket quality varies most, because the buyer cannot see the difference between a good CV joint and a poor one until it starts knocking at 20,000 km. We stock from suppliers who bench-test, and we say plainly which parts are tested and which are not.

Automatic transmissions: what is realistic to buy aftermarket
A complete automatic transmission is rarely worth shipping aftermarket — the core charge, the freight and the customs classification all work against it. What works is the component level: valve bodies, solenoid packs, clutch packs, bearings and seals for the DCT and CVT units that Chinese brands fit in volume.
For the 7-speed dry DCT used across Geely, Haval and Chery models, the wear items are the clutch pack, the mechatronic unit and the input shaft bearings. We supply all three, and we supply them as a matched set when a buyer is rebuilding rather than repairing, because mixing a new clutch pack with a worn mechatronic unit is what produces the judder that gets blamed on the parts.
Remanufactured units
Remanufactured CV axles and steering racks are available on a core-exchange basis. The core must be returned in the same shipment or the core charge stands. Remanufactured units are clearly labelled as such — a used part sold as remanufactured is a customs and a warranty problem, and we do not do it.
| Product | Condition | Core required | Warranty |
|---|---|---|---|
| CV axle assembly | New | No | 12 months |
| CV axle assembly | Remanufactured | Yes | 12 months |
| Steering rack | Remanufactured | Yes | 12 months |
| Clutch kit | New | No | 12 months / 30,000 km |
| Valve body (CVT / DCT) | New or tested used | No | 6 months |
MOQ, packing and lead time
CV axles are the awkward item in a mixed container: they are long, heavy and easy to bend. They ship in individual cardboard sleeves with a plastic cap on each spline, packed horizontally and strapped. Do not plan a loading layout that stands them on end.
| Item | MOQ | Lead time | Packing |
|---|---|---|---|
| Clutch kits (stock sizes) | 10 kits | 3–7 days | Kit box with bolts and tool |
| CV axles | 20 pcs (10 per side) | 15–25 days | Sleeve, spline caps, horizontal pack |
| Gearbox internals | 20 pcs per number | 20–30 days | Oil paper wrap, carton |
| Remanufactured units | 10 pcs | 20–30 days | Sleeve and foam, core return label |
Transmission & Drivetrain — questions buyers ask
Can you match a CV axle to a VIN? +
Yes, and for drivetrain parts it is the only reliable way. Chinese-brand models changed axle spline counts and ABS ring positions during facelifts without changing the model name. Send the VIN and we confirm the spline count, the length and the ABS ring before quoting.
Do you supply DCT clutch packs? +
Yes, for the 7-speed dry and wet DCT units used across Geely, Haval, Chery and BYD models. We supply the clutch pack, the mechatronic unit and the input shaft bearings, and we recommend replacing them as a set when the gearbox is already open.
What is the core charge on remanufactured parts? +
It is 30–40% of the unit price, refunded when the core arrives back at our warehouse in usable condition. Cores must be drained of oil and packed in the original sleeve. Cores returned after 90 days are not credited.
Are the CV boots nitrile or thermoplastic? +
Both are available. Nitrile is the cheaper option and is what most aftermarket kits use; thermoplastic boots last longer in hot climates and are worth specifying for the Middle East, North Africa and northern Australia. Say which market the goods are going to and we quote accordingly.
Can you supply a complete rebuilt transmission? +
For selected models, yes, on a core-exchange basis and usually by sea freight because of the weight. It is rarely economic for a first order. Most buyers start with valve bodies and clutch packs and only move to complete units once volume justifies it.
