Most used transmissions lose their label. Two or three photos from different angles are enough: we read the front case, the bolt hole positions and the differential, name the exact version, and check it will fit your vehicle.
Sample and trial orders are welcome, so you can test the quality before placing a container order.
Every offer names the exact condition of the part and the warranty that goes with it — remanufactured parts carry 6 months.
Or hand the goods over to your own forwarder in China — the export documents are prepared either way.
Bank transfer (XTransfer), PayPal, WeChat Pay or Alipay — details are on the proforma invoice.
