What the rebuild service covers
A rebuild engagement begins with a used transmission and ends with a finished unit that has passed the documented sequence and a full-load dyno inspection. Between those two points, the unit is fully disassembled, its parts are classified and recorded, failed parts are removed, reusable parts are ultrasonically cleaned and checked again, high-wear parts are replaced, known weak points are upgraded, components are bench tested, the housing is refurbished, and the unit is reassembled to a standard sequence. The service therefore covers the work on the unit itself, the testing of the finished unit, and the export packing described in the process. It does not, on this site, cover the sale of a new assembly or the sale of single parts to a specification table. Buyers who need a new assembly or a single part need a service that covers those subjects.
How the engagement runs
The buyer first states the transmission model code and the quantity required, because fitment and scope depend on the model. The incoming unit is then inspected on arrival: housings are checked for cracks and structural damage, and severe internal faults are identified before teardown. Units that pass enter the full sequence, while failed parts found during screening are scrapped rather than carried into reassembly. During the work, production tracking is listed among the services, so a buyer can ask how progress will be reported for the order. After reassembly, every finished unit goes through the full-load dyno inspection, and test data and a quality inspection record are retained for each unit. The finished unit is then checked against its model code, appearance, and sealing, and packed in an export fumigated solid wooden crate with shock and moisture protection.
What the buyer provides
The most useful thing a buyer can provide is an accurate transmission model code. A model code that is close but not exact can lead to the wrong scope, the wrong packing, or a unit that does not fit the intended vehicle. The buyer should also state the quantity, the destination, and any packing customisation required, and should confirm the trade terms and payment terms before payment. Where the buyer supplies the core, the buyer should confirm the core acceptance criteria and the core return terms before shipping, because a core that fails incoming inspection cannot enter the process in the same way as a core that passes. Clear information at the start prevents the most common sources of delay: uncertain fitment, an incomplete scope, and packing that does not suit the destination.
Rebuild, remanufactured, and reconditioned: how this site uses the words
In everyday use these words are often exchanged freely, which causes confusion when quotations are compared. On this site, transmission rebuild describes the service engagement, remanufactured transmission describes the finished unit that has passed the full documented sequence, and reconditioned transmission is treated as a separate comparison subject on its own page. The distinction is a matter of site organisation, not a claim about how other suppliers use the words. A buyer comparing suppliers should therefore look past the label and compare the step list, the screening rule, and the test coverage, since those three elements determine what the buyer actually receives.
Confirm before you order
- Please confirm the transmission model code, the quantity, and the destination in writing.
- Please confirm the minimum order quantity and the lead time before placing an order.
- Please confirm the scope of work, including any upgrades for known weak points that apply to your model.
- Please confirm what test data and quality inspection records will accompany each unit.
- Please confirm the packing, the trade terms, and the payment terms before payment.
Questions buyers ask
Do I need to send a core first?
That depends on the engagement. Some rebuild engagements start from a buyer-supplied core, while others draw on the core service described on this site. Please confirm the core arrangement, the acceptance criteria, and the return terms before shipping anything.
How will I know the rebuild was tested?
Every finished unit in the documented process receives a full-load dyno inspection, and test data and a quality inspection record are retained for each unit. Please confirm in writing what record will accompany your order.
What if my model code is uncertain?
Do not guess. Please confirm the model code from the unit itself or from the vehicle record, and ask for fitment to be confirmed in writing before placing an order.
