Dodge Nitro, KA (USA / CAN)

Additional Notes

• The transfer case fluid capacity of 0.85 liter applies uniformly across all listed Dodge Nitro AWD configurations, spanning both the 3.7 V6 and 4.0 V6 engines and all covered model years. A consistent capacity of this size is typical of a compact transfer case unit used in car-based SUV platforms, where the transfer case is relatively small compared to those found in body-on-frame trucks.
• For the Nitro 3.7 V6 AWD in 2006-2007, the normal-use service schedule specifies a check interval of 30,000 km or 30 months and a fluid change at 120,000 km or 120 months. The 120,000 km change interval represents a notably long service life for transfer case fluid under normal operating conditions.
• Under severe-use conditions for the 2006-2007 Nitro 3.7 V6 AWD, the fluid change interval drops to 60,000 miles, exactly half the distance threshold associated with the normal-use 120,000 km change interval. Severe use typically encompasses conditions such as frequent towing, off-road driving, or repeated short trips that accelerate fluid degradation.
• The Canadian-market specification for the 2006-2007 Nitro 3.7 V6 AWD under normal use lists a fluid change at 100,000 km or 60 months. This differs from the USA normal-use change interval of 120,000 km or 120 months for the same engine and model years, reflecting a regional variation in service scheduling.
• For the 2007-2010 Nitro 3.7 V6 AWD, the normal-use row specifies only a check interval of 30,000 miles or 30 months, with no change interval listed. The severe-use row for the same configuration carries only a change interval of 60,000 miles or 60 months, with no check interval listed. The two use conditions together cover distinct service actions rather than duplicating them.
• The 4.0 V6 AWD configurations for 2007-2010 follow the same interval structure as the 3.7 V6 AWD for the same years: a normal-use check at 30,000 miles or 30 months and a severe-use change at 60,000 miles or 60 months. The identical scheduling across both engine variants in this period indicates that the transfer case unit and its service requirements were shared regardless of engine displacement.
• Beginning with the 2010-2012 model years, both the 3.7 V6 and 4.0 V6 AWD configurations shift to a normal-use check interval of 32,000 km or 24 months. The previous 2007-2010 normal-use interval was expressed in miles at 30,000 miles or 30 months, so the 2010-2012 entries represent both a unit change to kilometers and a reduction in the time-based threshold from 30 months to 24 months.
• The severe-use change interval for both the 3.7 V6 and 4.0 V6 AWD in 2010-2012 is listed as 64,000 miles or 48 months. Compared to the 2007-2010 severe-use interval of 60,000 miles or 60 months, the distance threshold increases slightly while the time-based threshold shortens from 60 months to 48 months.
