48RE Transmission: Extreme-Duty Strength, Advanced Control, and Proven Diesel Performance for Your Dodge/Ram Truck

The 48RE transmission is a heavy-duty four-speed automatic transmission developed by Chrysler, designed as the evolution of the 47RE. Built specifically for high-output diesel applications, the 48RE is most commonly paired with the legendary 5.9L Cummins engine in Ram Trucks heavy-duty pickups.

Engineered for both rear-wheel drive (RWD) and four-wheel drive (4WD) configurations, the 48RE delivers enhanced torque capacity, improved electronic control, and superior durability—making it a top-tier choice for towing, hauling, and high-performance diesel builds.

Key Features of the 48RE Transmission

Four-Speed Automatic Transmission with Overdrive

The 48RE offers four forward gears, including overdrive, delivering strong low-end torque for towing while maintaining efficient highway RPMs.

Enhanced Electronic Control System

Building on the 47RE platform, the 48RE features refined electronic governor pressure control via the Powertrain Control Module (PCM), resulting in smoother, more precise shift timing and improved drivability under load.

Increased Torque Capacity

Designed to handle the higher output of later-model Cummins engines, the 48RE supports significantly greater torque loads than its predecessor—making it ideal for heavy towing and performance applications.

Heavy-Duty Internal Upgrades

Compared to the 47RE, the 48RE includes stronger clutch packs, upgraded bands, improved valve body calibration, and reinforced internal components to handle increased stress.

Proven Diesel Durability

The 48RE has built a strong reputation in real-world work environments, especially in trucks used for commercial hauling, towing, and off-road applications.

Highly Upgradeable Platform

The 48RE is extremely popular in the diesel performance world, supporting upgrades such as billet input/output shafts, upgraded valve bodies, shift kits, and high-performance torque converters.

Common Applications of the 48RE Transmission

The 48RE transmission is primarily found in Dodge/Ram trucks equipped with diesel engines. Typical applications include:

  • Dodge Ram 2500 (2003–2007) – Paired with the 5.9L Cummins diesel

  • Dodge Ram 3500 (2003–2007) – Built for heavy-duty and commercial-grade workloads

  • High-output Cummins applications – Including performance and towing builds

Why Choose the 48RE Transmission for Your Truck?

The 48RE is built for drivers who demand maximum strength and reliability. Whether you’re towing heavy loads, operating a fleet vehicle, or pushing a performance diesel build, the 48RE provides:

  • Improved durability over the 47RE

  • Better electronic control and shift quality

  • Higher torque-handling capability

  • Proven reliability in extreme-duty conditions

Its balance of mechanical simplicity and electronic control makes it both powerful and serviceable—an ideal combination for long-term ownership.
