The Sun Coast 10L1000 Category 3 Transmission is the pinnacle of heavy-duty transmission engineering, crafted to meet the demands of high-torque, high-performance environments. This transmission is based on the Allison 10L1000, a result of a collaboration between Allison and Ford, and further enhanced by Sun Coast’s expertise to offer a robust solution for extreme applications.

At the core of the Category 3 transmission is the Pro Loc Valve Body and Pump Assembly, which addresses the critical issues that arise in heavy-duty use, such as towing, hauling, and high-performance driving. This assembly increases overall line pressure by up to 60psi, enhancing the clamping force on all clutch packs and ensuring more reliable shifts under load. The Pro Loc Valve Body also improves lock-up apply pressure, reducing turbine slip and enhancing torque converter clutch longevity. Additionally, the lubrication circuit is modified to increase cooler charge pressure by 250%, significantly improving heat dissipation and preventing premature failure.

The transmission also features an Expanded Capacity E Drum, which provides a 29% increase in clutch capacity over the OEM drum. This drum is equipped with a billet 6061 apply piston, designed to eliminate deflection and ensure consistent performance under high line pressures. Sun Coast’s patent-pending design and in-house CNC machining guarantee the highest levels of precision and durability.

The friction material used in the Category 3 transmission is Raybestos GPZ, renowned for its ability to withstand high stress, temperatures, and repeated cycling. This material outperforms OE standards by up to 20%, ensuring better shift performance, enhanced durability, and greater torque capacity.

To complement these internal upgrades, the Sun Coast 10L1000 Category 3 Transmission includes a deep cast aluminum pan, adding 4 quarts of fluid capacity over the stock pan. The finned design enhances heat dissipation, maintaining optimal transmission temperatures even during extended operation.

This transmission also features a Guardian Torque Converter, designed to manage the extreme forces generated by heavy-duty applications. The converter’s advanced lock-up technology ensures smooth and reliable torque transfer, contributing to the overall longevity and performance of the transmission.

With the Sun Coast 10L1000 Category 3 Transmission, you’re investing in a solution that not only meets but exceeds the demands of the toughest work environments. It’s engineered for those who require maximum reliability, durability, and performance from their vehicle’s transmission, ensuring peace of mind on every job.
