Transmission Cooler for BYD F3: Cast Iron
This transmission cooler for the BYD F3 is specified around cast iron, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is reorders that did not match the approved sample, or inconsistent hardness between lots. Both are specification problems, and both are preventable.

Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. TUV documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
