ATS Diesel 2003-2004 Cummins 48RE Modified Towing Valve Body | 3039022272

ATS 48RE Towing valve body

The throttle valve in the valve body sets shift timing and the line pressure that clamps the clutches and band. In the factory Dodge valve body, that valve tends to stick or wear its bore, which leads to poor shifts.

ATS fixes this with a hydro-balanced valve running in a hardened sleeve, similar to a sleeve in an engine block. The sleeve keeps the bore from wearing, and the new valve shape lets ATS raise line pressure without harsh, banging shifts.

The Towing version is calibrated for firm, consistent shifts under load.

Who it's for

Owners of a 2003-early 2004 Dodge Ram 2500/3500 5.9L Cummins with a 48RE who want firm, reliable shifts while towing.
