The BD Diesel 1064234F TowMaster is a rebuilt 48RE automatic for 2005-2007 Dodge Ram 2500/3500 4WD trucks with the 5.9L Cummins. This 2005-2007 unit is built for trucks with the TVV stepper motor. The stock 48RE was built for factory power, so added fuel, larger tires and heavy trailers lead to soft shifts, burned clutches and heat. This transmission adds clutch capacity and line pressure for street and towing use.

BD installs a revised valve body for higher apply pressure, upgrades the governor solenoid and transducer, replaces stock thrust washers with Torrington roller bearings, and ships each unit with a deep aluminum pan and an auxiliary full-flow filter kit. Each transmission is dyno tested. This is the transmission only; a BD torque converter must be installed with it to keep the warranty. Core required, refundable deposit at checkout.

Key Features & Benefits

• Increased Clutch Count: Forward 5, direct 6, overdrive 6 and overdrive direct 10, with a high-temp Raybestos band.
• Higher Line Pressure: Revised valve body targets about 190-200 psi apply pressure without shuttle shifting.
• Durability Upgrades: Torrington roller bearings replace stock thrust washers; drilled intermediate shaft and cooler-line case saver.
• Deep Pan: BD rigid aluminum pan adds about 2 quarts of fluid capacity and helps reduce case flex.
• Full Flow Filter Kit: Auxiliary frame-mounted filter kit included for added protection.
