BD Diesel 1065042SS Towmaster Transmission & Converter Package AISIN AS69RC 2WD Left-Hand PTO

The BD Diesel 1065042SS Towmaster Transmission & Converter Package is a performance-remanufactured AISIN AS69RC automatic transmission built for 2WD Ram 3500–5500 trucks equipped with a factory left-hand (LH) PTO provision. This is a special-order configuration designed for diesel trucks that demand more than a stock transmission can deliver.

The AS69RC platform is well-known for excessive spline wear on the K2 hub — a weakness BD Diesel directly addresses with a proprietary nitride billet K2 hub. A billet K3 drum is added for increased clutch capacity and structural rigidity, while friction counts are increased across the K2, K3, and B1 clutch packs to significantly raise overall torque capacity. Frictions are custom-selected to preserve smooth, reliable shift quality rather than sacrificing drivability for raw holding power.

Key Features & Upgrades:

• Nitride Billet K2 Hub — resolves the notorious clutch tooth wear issue found in stock AS69RC transmissions
• Billet K3 Drum — improves clutch capacity, rigidity, and resistance to ring groove failure
• Increased Friction Counts — upgraded K2, K3, and B1 clutch packs for higher torque capacity
• Custom-Selected Frictions — maintain smooth, consistent shift quality under load
• Improved Nitrile Gaskets — replace leak-prone factory cork gaskets on the pan and PTO
• BD ProForce Torque Converter — OE-style converter included and matched to the transmission
• 2WD Left-Hand PTO Configuration — special-order build for trucks with a factory LH PTO provision

Important Note: This part number (1065042SS) is specifically for 2WD trucks with a left-hand PTO provision. If your truck has a right-hand PTO, order part number 1065012PTOSS. If your truck has no PTO provision, order part number 1065012SS. Verify your factory PTO configuration before ordering.

BD Diesel transmissions are remanufactured — not simply rebuilt — with upgraded internals designed to withstand heavy towing, high horsepower, and repeated heat cycles. This package ships LTL freight and requires a core return.
