Dodge Ram Ram Chassis Cab, DR/DH/D1/DC/DM (USA / CAN)

Additional Notes

• The Dodge Ram Chassis Cab 3500 5.9 D (4x2) manual transmission carries two distinct fluid capacities across the 2004-2007 model years: 3.79 liters and 4.5 liters. The presence of two separate capacity figures for the same engine and drivetrain configuration indicates that more than one manual transmission unit was fitted to the 3500 during this period.
• A capacity of 3.79 liters is a common service fill figure for medium-duty manual transmissions, representing the amount of fluid required to bring a drained unit back to the correct operating level without a full disassembly.
• The larger 4.5-liter capacity figure is consistent with a heavier-duty or physically larger transmission housing, which holds a greater total fluid volume to support the thermal and load demands of a diesel-powered chassis cab application.
• Both the 3.79-liter and 4.5-liter capacities are listed under normal use conditions, meaning neither figure is associated with a severe-duty service interval or a first-change-only specification.
• The same pair of capacity values, 3.79 liters and 4.5 liters, appears identically for both the Canadian and United States market variants of the Ram Chassis Cab 3500 5.9 D (4x2), indicating no regional difference in manual transmission fluid volume requirements between the two markets for this configuration.
