Automatic Transmissions
For the growing family of Dodge Ram Heavy Duty work trucks, the 68RFE 6-speed automatic transmission is available. Available for Ram Heavy Duty 2500 and 3500 pickups (in both single- and dual-rear-wheel configurations) and masterfully equipped with the available 6.7-liter Cummins® Turbo Diesel, the 6-speed automatic provides benefits measured by the best criteria for business today: strength, stamina, and reliability.
One of the most popular choices in combination with the 5.7-liter HEMI® V8 is the available and long-proven 5-speed automatic transmission. The 545RFE five-speed features a specialized fifth gear—available as an additional overdrive ratio to provide increased fuel economy[1] [2] and reduced engine noise at highway speeds.

Six-Speed Manual
This transmission is built for heavy-duty work, and is the standard transmission for all Ram Heavy Duty models. A principal feature is the ultralow first gear ratio—as low as 6.29:1—which is ideal for heavier hauling requirements.
