Aisin Seiki AS68RC Transmission Pump (2007–2011)
The Aisin Seiki AS68RC transmission pump delivers consistent hydraulic pressure for vehicles equipped with the AS68RC 6-speed automatic transmission from 2007 through 2011. This pump regulates fluid flow throughout the transmission, ensuring proper clutch engagement, lubrication, and smooth gear shifts under load. Because the AS68RC is commonly used in heavy-duty diesel applications, the pump plays a critical role in maintaining durability and towing performance.
Over time, internal wear, scoring, or pressure loss can reduce pump efficiency. As a result, drivers may notice slipping, delayed engagement, overheating, or harsh shifting. Replacing the AS68RC transmission pump restores correct line pressure and improves overall transmission operation. In addition, installing a new pump during a rebuild protects internal clutches and planetary components from premature wear. Always confirm that your vehicle uses the AS68RC transmission, since similar Aisin units may require different pump configurations.
This AS68RC pump assembly works best when installed during a complete overhaul or major service. For example, pairing it with new seals, bushings, and a rebuild kit ensures balanced hydraulic performance and long-term reliability.
