A service category, not a product catalogue
Continuously variable transmissions are treated on this site strictly as a remanufacturing service category. That means this page explains the service applied to continuously variable units, the checks that service includes, and the points a buyer should confirm. It does not list continuously variable models, does not publish a specification table for any continuously variable part, and does not describe continuously variable products for sale as new units.
The remanufacturing service for continuously variable units
The service follows the documented 10-step process, adapted where the process specifies a continuously variable check. The incoming unit is inspected for housing cracks, structural damage, and severe internal faults, and only units that pass enter the process. The unit is fully disassembled, and parts are classified, registered, and numbered. Core parts are screened, and parts showing wear, deformation, fatigue, or out-of-tolerance measurements are scrapped. Reusable parts are ultrasonically cleaned in repeated cycles and checked again. High-wear parts are replaced, and upgrades are applied to known weak points in the original design. Pressing uses 20-ton hydraulic equipment, and worn valve bores are repaired with sleeves. Component bench testing covers solenoids, sensors, and valve body assemblies for oil flow, pressure stability, switching response, and sealing, and continuously variable units receive an additional pulley cylinder pressure check, which examines internal leakage and pressure loss. Housings are refurbished and sealing surfaces prepared. Reassembly follows the original assembly method, torque parameters, and lubrication rules. Every finished unit is dyno tested under full load, with no sampling, and its test data and quality inspection record are retained. The finished unit is finally inspected and packed in an export fumigated solid wooden crate.
Why the continuously variable check matters
Continuously variable transmissions control ratio through pulleys and a belt or chain, and their hydraulic control must hold pressure precisely for the ratio to behave correctly. Internal leakage or pressure loss in the pulley cylinder therefore presents as a driving fault that a general inspection may miss. The additional pulley cylinder pressure check in the documented process addresses that specific risk for continuously variable units. A buyer comparing a continuously variable remanufacturing service with a general automatic service should ask whether that check is included for the model code in question, because a service that omits it leaves a category-specific risk unexamined. Please confirm the bench testing scope for your model code in writing before placing an order.
Fitment and scope for continuously variable units
As with automatic units, the transmission model code is the essential identifier. A buyer should confirm the model code from the unit or the vehicle record, and should ask for fitment and scope to be confirmed in writing before placing an order. The scope for a continuously variable model should be stated for that model, including the pulley cylinder pressure check and any upgrades for known weak points that apply to that model. A scope borrowed from an automatic model, or from another continuously variable model, should not be assumed to apply. Please confirm the transmission model code, the quantity, and the destination before placing an order.
Confirm before you order
- Please confirm the transmission model code and that the unit is a continuously variable unit, in writing.
- Please confirm the scope of work for that model, including the pulley cylinder pressure check.
- Please confirm the minimum order quantity and the lead time before placing an order.
- Please confirm that the 100% dyno inspection applies to every unit in your order.
- Please confirm what test data and quality inspection records will accompany each unit, together with the warranty terms, the packing, the trade terms, and the payment terms, before payment.
Questions buyers ask
Is this a continuously variable product page?
No. This is a remanufacturing service page for continuously variable units. It describes the service, not a product range, and it does not list models or part specifications.
Does the service cover belt or chain parts specifically?
The documented process covers the unit as a system, including screening, cleaning, renewal, bench testing, and the pulley cylinder pressure check. Please confirm the scope for your exact model code in writing, rather than assuming coverage for a particular part.
How is a finished continuously variable unit tested?
As with other finished units, every finished unit is dyno tested under full load, with no sampling, covering main line oil pressure, clutch engagement, torque output, shift smoothness, working temperature, hydraulic condition, abnormal noise, and sealing, for the continuously variable unit under test. Please confirm the test items for your model code in writing.
