Thumbnail Filmstrip of 5.9 Cummins Towmaster 48RE Transmission & Converter Package With TVV Stepper Motor BD 1064234SS Images
When you are demanding more from your 2005–2007 5.9L Cummins (4WD with a TVV Stepper Motor), the factory drivetrain components quickly become the weakest link. The BD Diesel 1064234SS Towmaster 48RE Transmission & Converter Package is engineered as a perfectly matched, dyno-tested set designed to handle the massive torque loads of heavy towing, street performance, and daily driving. By pairing a heavily reinforced transmission with a high-efficiency torque converter, this package eliminates the common failure points of the stock 48RE, ensuring that your diesel's power actually makes it to the ground with ultimate reliability.
- Advanced Hydraulics & Control: Features an upgraded valve body, an upgraded governor solenoid, and a heavy-duty governor pressure transducer with twice the burst pressure of stock to completely eliminate shuttle shifting. Line pressure is boosted to a commanding 190–200 psi.
- Enhanced Internal Lubrication: Includes a modified manual valve for lubrication in all gear positions, stock thrust bushings replaced with premium roller Torrington bearings, and a drilled intermediate shaft for superior oil flow.
- Robust Clutch & Band Packs: Built for durability with an increased clutch count (6 Direct, 5 Forward, 6 OD, 10 OD Direct) and a high-temperature, high-energy Raybestos band.
- Heavy-Duty Input Shafts: Equipped with a billet input shaft and a Billet "Big" fine spline input shaft to prevent shearing under heavy loads.
- Premium Fluid Management: Includes a rigid aluminum heavy-duty BD transmission pan that adds 2 quarts of extra oil capacity, features heat-dissipating fins, and utilizes a magnetic drain plug. A cooler line case saver and a BD auxiliary full-flow filter kit provide maximum filtration and drivetrain protection.
- ProForce 3D Triple Disc Torque Converter: Features a stamped-forged 1-piece cover to eliminate warpage, self-centering trapezoid teeth to decrease wear and chatter, heavy-duty shock-absorbing engagement springs, and furnace-brazed turbine fins. It utilizes robust thrust bearings instead of plastic washers and a riveted piston to eliminate vibration.
- ProForce Street/Towing Stall Optimization: Offers an enhanced stall speed tailored for street and towing applications. The torque-multiplying cast aluminum stator delivers lower RPM response than a stock converter, leading to more efficient operation, reduced heat buildup, and improved fuel economy.
Investing in the BD Diesel Towmaster package means choosing a comprehensive drivetrain solution where every single component has been optimized for longevity and thermal efficiency. Because every unit is fully tested on a dynamometer before leaving the facility, you can hook up to your trailer with absolute confidence. Please note that while this package is the clear choice for dependable street and towing performance, it is not warranted for race or sled-pull use.
