Why buyers choose Mingfeng

TRANSFENG is our own brand — automatic transmission assemblies and components, quoted item by item from photos of the actual stock.

✓
20 years in automatic transmissions

Assemblies and components supplied to importers, rebuilders and repair shops worldwide.

✓
The exact part in writing, before you pay

Every offer states the part, the transmission code it suits and the condition of the item.

Photos of the real unit, not a catalogue picture

We shoot the actual part in our Guangzhou stock and send the pictures with the quotation.

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.

✓
One-piece minimum

Sample and trial orders are welcome, so you can test the quality before placing a container order.

✓
Condition and warranty stated per item

Every offer names the exact condition of the part and the warranty that goes with it — remanufactured parts carry 6 months.

✓
Export packing, air / sea / courier

Or hand the goods over to your own forwarder in China — the export documents are prepared either way.

✓
Payment the way buyers ask

Bank transfer (XTransfer), PayPal, WeChat Pay or Alipay — details are on the proforma invoice.
