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

Additional Notes

• The dry fill capacity of 13.7 to 15.61 liters applies across all configurations listed for the Dodge Ram Chassis Cab 3500 in both the 5.7 V8 and 5.9 diesel variants. Dry fill represents the total fluid volume required when filling a completely empty transmission, such as after a full overhaul or unit replacement.
• Service fill capacity, which reflects the smaller volume needed after a routine drain and refill, varies by drivetrain configuration on the 5.7 V8. The 4x2 configuration carries a 5.2-liter service fill, while the 4x4 configuration requires 6.15 liters, a difference attributable to the additional fluid retained in the transfer case circuit or related components.
• The 5.9 diesel variants introduce a second service fill value of 3.79 liters alongside the 5.2-liter figure, indicating that two distinct service fill quantities apply depending on which service procedure or fluid circuit is being addressed.
• For the 5.7 V8 in model years 2007-2008, the change interval under normal use conditions is set at 48,000 km or 24 months, whichever comes first. This time-based component means the interval can be reached through calendar time alone, regardless of mileage accumulation.
• The 2009 model year 5.7 V8 configurations show a substantial revision to the normal-use change interval, extending it to 200,000 km or 120 months. This represents a significant departure from the 48,000 km interval specified for the same engine in 2007-2008.
• Under severe use conditions in 2009, the 5.7 V8 change interval is listed at 100,000 km or 60 months, exactly half the normal-use interval for that same year. Severe use conditions typically encompass operating environments such as frequent towing, extreme temperatures, or stop-and-go driving patterns that accelerate fluid degradation.
• The Canadian-market Ram Chassis Cab 3500 5.9 diesel (4x2) for 2004-2007 lists two separate normal-use change intervals: 48,000 km tied to the 3.79-liter service fill, and 96,000 km tied to the 5.2-liter service fill. This pairing suggests the two service fill values correspond to different service procedures performed at staggered intervals.
• The USA-market 5.9 diesel (4x2) for 2004-2007 lists no change interval for the normal-use condition on either service fill value, while the severe-use condition carries intervals of 48,000 km for the 3.79-liter fill and 96,000 km for the 5.2-liter fill. The presence of intervals only under severe use reflects a market-specific service schedule structure distinct from the Canadian specification.
