Product Description
The ATS 303-900-3368 6R140 Performance Valve Body is a critical upgrade for 2011+ Ford Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. Designed to improve transmission performance, shift quality, and durability, this valve body upgrade addresses common weaknesses in the factory 6R140 transmission.
ATS modifies the valve body to increase line pressure, improve clutch engagement, and deliver more consistent, firm shifts under load. These improvements help reduce clutch slippage, minimize heat buildup, and extend overall transmission life—especially in towing, hauling, and performance applications.
Whether your truck is stock or modified, the ATS 6R140 Performance Valve Body is engineered to provide better control, reliability, and performance in demanding diesel environments.
