47re transmission

Specifications

The 47RE transmission is a heavy-duty 4-speed automatic transmission developed by Chrysler, primarily used in Dodge Ram 2500 and 3500 trucks from the mid-1990s to the early 2000s. It is an evolution of the A727 design, enhanced with electronic controls for precise shift management and an overdrive gear for improved highway efficiency. Designed to handle high torque, especially from diesel engines, it features a fully electronic valve body, torque converter clutch, and a robust gearset capable of handling substantial towing loads. 

Despite its strength, the 47RE is known for limitations under extreme power, often requiring aftermarket upgrades such as billet input shafts, drum kits, and reinforced valve bodies to improve reliability and durability in high-performance or heavy-towing applications.
