Stage 1 4R100 Transmission Package

The ATS Diesel Performance 309-914-3224 is a Stage 1 4R100 transmission package engineered to enhance the durability and performance of 1999-2003 Ford F-250, F-350, and F-450 4WD diesel trucks equipped with the 7.3L Powerstroke engine and 4R100 transmission. The factory Ford 4R100 transmission is known to develop weaknesses in its torque converter, clutch pack assemblies, valve body, and line pressure capabilities, especially when the engine's power is increased or during towing applications. This ATS Stage 1 package directly addresses these vulnerabilities by re-designing and improving critical components. Key enhancements include increased line pressure, greater clutch pack surface area, and modifications to the valve body, all contributing to a more consistent, responsive, and dependable transmission. The Stage 1 package is specifically tailored for trucks used in daily driving and towing scenarios, as well as those with minor modifications such as an upgraded air intake, exhaust, or a mild tune. Features of the ATS Diesel 309-914-3224 include the ATS Five Star Torque Converter, which boasts a billet cover, five lock-up clutches, a billet stator, and a furnace-brazed impeller for superior strength and performance. The transmission pump has been modified for increased line pressure, and the package includes high-performance clutch packs with more surface area than stock units. Redesigned accumulator pistons ensure a precise shift feel, and the kit comes complete with an ATS Deep Transmission Pan. This pan increases fluid capacity by 5 quarts, features a finned design for improved cooling, a magnetic drain plug, and is tapped to accommodate a temperature probe. This transmission package is backed by an ATS 5-year/500,000-mile warranty, offering significant peace of mind regardless of the power level or usage of your truck. The kit is sold as a complete package for comprehensive upgrade.
