Product Description
The BD DIESEL 1030410 Valve Body Exchange is a performance-engineered upgrade for 1991–1993 Dodge trucks equipped with the 5.9L Cummins diesel and the 518 (46RH) automatic transmission. This BD-built valve body is designed to correct common factory shortcomings by increasing line pressure, improving shift timing, and significantly enhancing clutch holding capacity.
By recalibrating hydraulic circuits and valve body components, this exchange unit delivers firmer, more positive shifts, reduced clutch slippage, and improved transmission durability — especially important for trucks used for towing or heavy work. This valve body is supplied as an exchange unit and requires a refundable core.
