Product Description
The ATS 303-903-3224 4R100 Accumulator Valve Body is a performance-enhancing upgrade designed for 1999-2003 Ford Super Duty trucks equipped with the 7.3L Powerstroke diesel engine and 4R100 automatic transmission. This upgraded valve body is engineered to improve shift quality, increase line pressure control, and enhance overall transmission durability.
The factory 4R100 valve body is known for soft shifts and premature clutch wear under load. ATS addresses these issues by recalibrating hydraulic circuits and accumulator functions to provide firmer, more controlled shifts while reducing slippage and heat buildup. The result is improved transmission efficiency, longer component life, and better performance under towing or heavy-duty conditions.
This upgrade is ideal for stock or modified trucks and is especially beneficial for vehicles used in towing, hauling, or performance applications where transmission reliability is critical.
