Isuzu NPR

Manual transmission fluid capacity & service interval

Isuzu NPR manual transmission fluid capacity ranges from 2,6 to 3,2 liters. Service intervals include checks at 10000 km and changes at 40000 km or 24 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across the Isuzu NPR lineup covered by these specifications, manual transmission fluid capacities fall into three distinct values: 2.6 liters, 2.7 liters, and 3.2 liters, reflecting differences in the physical size and gear count of the transmissions fitted to each variant.
  • The NPR 58 and NPR 59 share an identical 2.6-liter capacity, both covering the 1996-2007 model years under normal use conditions.
  • The NPR 69 carries a 2.7-liter capacity, placing it between the smaller 2.6-liter units and the larger 3.2-liter transmissions found in other variants of the same generation.
  • The NPR 62, NPR 65, and NPR 66 all specify a 3.2-liter capacity. A larger fluid volume in a manual transmission generally corresponds to a heavier-duty gearbox designed for higher torque loads or additional gear ratios.
  • The NPR 62 has a starting model year of 1998, two years later than the 1996 start date shared by the NPR 58, NPR 59, NPR 65, NPR 66, and NPR 69.
  • All six variants share the same fluid check interval of every 10,000 km under normal use. Periodic checks at this interval allow detection of fluid level loss or contamination before the scheduled drain interval is reached.
  • The fluid change interval for all listed variants is 40,000 km or 24 months, whichever comes first. The inclusion of a time-based limit of 24 months means fluid is replaced even when mileage accumulation is low, accounting for fluid degradation over time independent of use.
