Product Overview

The BD Diesel 1064304 RoadMaster 68RFE Transmission is a high-reliability replacement for the stock 68RFE, specifically designed for 2019–2024 RAM 2500 and 3500 6.7L Cummins 4WD trucks. Engineered for towing, daily driving, and moderate tuning, this transmission includes BD’s proven Protect68 Valve Body to eliminate cross leaks—a common cause of 68RFE failure.

Supporting the upgraded hydraulics is BD’s Pressure Enhancer Module, increasing line pressure up to 220 PSI to boost torque-holding capability. A billet 4C spring retainer provides improved clutch stability under load, while the deep sump pan improves cooling and fluid volume, ideal for heavy-duty applications.

If you're seeking a transmission upgrade that prioritizes durability, factory functionality, and better thermal management, this is an excellent choice for builds staying within stock or stock-plus injector limits.
