Dodge Ram Ram 2500, BR/BE (USA / CAN)

Additional Notes

• The Dodge Ram 2500 BR/BE 5.9 D V8 4x4 configurations from 1994-1998 carry three distinct transfer case capacity values: 1.2 liters, 2.2 liters, and 3.1 liters. The presence of three separate capacity figures across the same engine variant reflects the use of different transfer case units, each with a different fluid volume requirement.
• The 3.1-liter capacity figure appears exclusively in the 1994-1998 diesel V8 configurations. A transfer case holding 3.1 liters of fluid is associated with a larger, more robust unit, typically found in heavier-duty four-wheel-drive applications where greater torque handling is required.
• For the 1994-1995 diesel V8 configurations, both the 120 kW and 130 kW output variants share identical transfer case capacities of 1.2, 2.2, and 3.1 liters, all under a normal-use service interval of 57,600 km or 36 months.
• The 1996-1998 model years introduced a higher-output 160 kW diesel V8 variant alongside the continuing 130 kW version. Both share the same three transfer case capacity options and the same 57,600 km / 36-month change interval under normal use conditions.
• A notable shift occurs with the 1999-2001 configurations, where the service interval changes from a kilometer-based measurement to a mileage-based one: 37,500 miles or 30 months under normal use. The 30-month time limit is also shorter than the 36-month limit applied to the 1994-1998 entries.
• The 1999-2001 entries list only two transfer case capacities — 1.2 liters and 2.2 liters — compared to the three capacity options present in earlier model years. The 3.1-liter capacity does not appear in the 1999-2001 specifications.
• The 1999-2001 range includes both a diesel (5.9 D V8) and a gasoline (5.9 V8) variant, each sharing the same two transfer case capacity values of 1.2 and 2.2 liters and the same 37,500-mile / 30-month normal-use interval.
• The 1.2-liter capacity value, present across all model years and engine variants in the specifications, represents the smallest transfer case fluid volume listed. Smaller-capacity transfer cases of this type are generally associated with part-time four-wheel-drive systems with a more compact internal design.
