Product Description
The ATS 303-102-2116 A618 Towing Valve Body is a purpose-built upgrade for 1990-1993 Dodge Ram trucks equipped with the 5.9L Cummins diesel engine and A618 automatic transmission. Designed specifically for towing and heavy-duty applications, this valve body improves transmission performance, durability, and shift control under load.
The factory A618 valve body is known for soft shifts and insufficient line pressure when towing or under increased stress. ATS addresses these issues by recalibrating hydraulic circuits to increase line pressure, reduce clutch slippage, and deliver firmer, more controlled shifts.
This towing valve body is ideal for work trucks, heavy hauling, and diesel owners looking to improve transmission reliability while maintaining smooth drivability. By optimizing fluid flow and clutch engagement, ATS helps extend transmission life and reduce wear on internal components.
