Product Description
The BD DIESEL 1030423-FM Full Manual Valve Body is designed for maximum driver control and durability in 2003–2007 Dodge Ram trucks equipped with the 48RE automatic transmission. This full manual valve body eliminates automatic shifting and places complete shift control in the driver’s hands, making it ideal for racing, sled pulling, drag applications, and extreme-duty use where shift consistency is critical.
BD Diesel engineers this valve body to deliver positive, firm shifts with no shift overlap, reducing clutch slippage and heat buildup under high load. The full manual configuration removes electronic shift commands, allowing predictable gear changes at any RPM. This unit is intended for off-road and competition use where drivability tradeoffs are acceptable.
