Key Features & Benefits

This is a professional remanufactured kit containing the core pulley assemblies and drive chain for the Hyundai/Kia Kappa CF12 Continuously Variable Transmission (CVT). The Kappa CF12 CVT is a compact transmission used in small vehicles, with the CF12 variant designed for 1.4L engines.

• Complete Pulley System Solution: The kit includes both the primary (drive) and secondary (driven) pulley assemblies along with the critical steel drive chain. This addresses the most common and significant failure points in this CVT design.

• Addresses Core CVT Issues: Remanufacturing these components directly tackles the root causes of common problems such as shuddering during acceleration, loss of drive, belt/chain slippage, and abnormal noises, which often originate from worn pulley sheaves, failing hydraulics, or a stretched chain.

• Professionally Remanufactured: The kit has undergone a complete industrial process involving disassembly, cleaning, replacement of all wear components (seals, bearings, friction materials), machining of critical surfaces, reassembly, and testing to meet performance standards.

• Cost-Effective & Reliable: Offers a more affordable and environmentally friendly alternative to purchasing all-new OEM pulleys and chain, while providing restored, reliable performance backed by a warranty.

Service & Installation Notes

• Professional Installation Required: This is a major transmission overhaul component. Installation requires complete transmission disassembly and should only be performed by a technician specialized in CVT repair.

• Complete System Service: It is highly recommended to also replace the transmission fluid filter and perform a complete fluid exchange using the specified fluid (Hyundai ATF SP-CVT 1).

• System Adaptation: After installation, a transmission control module (TCM) adaptation procedure using professional diagnostic equipment is mandatory for proper calibration and operation.
