2007.5-2018 Cummins Trackmaster Transmission & Converter Package 68RFE (106426XBM)

Fits

The BD TrackMaster 68RFE transmission is engineered for durability in high-load settings, ideal for modified Cummins RAM trucks. It features a reinforced valve body, billet input shaft, and HD billet OD drum to boost clutch pack torque by almost 50%. The oversized HD OD drum, Big Stack OD clutch pack, and ProTech68 valve body maintain strong 250psi pressure. A BD Diesel Deep aluminum pan adds 4.5 quarts of fluid capacity to help lower transmission heat during towing. Each package includes a billet ProForce 3D stall torque converter and is dyno tested for performance. 

Part Number: 1064263BM / 1064265BM 

Transmission:

• ProTech68 valve body: Hard-anodized with gasket to prevent internal leaks.
• Pressure controller module: Ramps line pressure to 250 psi, referencing MAP sensor for load.
• TCC limit valve & SSV bore: Sleeved/machined to reduce wear and leaks.
• Accumulator & piston upgrades: Thicker steel accumulator plate, billet steel 2C piston girdle, and BD QT100 pressure plates increase clutch capacity and reduce deflection.
• Clutch improvements: More clutches (33% increase on C2 & OD), stronger OD drum, Big Stack OD shaft for increased torque capacity.
• Heavy-duty sprag & retainers: Cam & roller low-reverse sprag, billet 4C spring retainer.
• Fluid management: Deep aluminum pan adds 4.5 quarts for cooler operation.
• Clutch counts: OD 8+8, Rev 2+2, 2C 3+3, 4C 3+3, UD 5+5, LR 7+7.

Billet ProForce 3D Torque Converter:

• Enhanced stall for street/towing.
• Durable construction: HD springs, stamp-forged one-piece cover, riveted pistons, thrust bearings.
• Improved clutch & stator design: Increases contact, reduces wear/chatter, maximizes torque.
• Efficiency upgrades: Self-centring trapezoid clutch teeth, furnace-brazed turbine fins.
