Isuzu N-series

Automatic transmission fluid capacity & service interval

Isuzu N-series automatic transmission fluid capacity is 9,2-9,5 liters. Service intervals include checks at 40000 km and 60000 km, with changes at 100000 km/60 months or 800000 km. The data covers 4 configurations.

Additional Notes

  • The Isuzu N-Series 1.9 DPF in NLR87 and NNR87 configurations carries an automatic transmission fluid capacity range of 9.2-9.5 liters for the 2021-2024 model years, while the 2024 starting year configuration specifies a slightly narrowed range of 9.3-9.5 liters, indicating a tighter lower bound on the service fill volume.
  • A capacity expressed as a range rather than a fixed figure typically reflects variation between a drain-and-fill service quantity and a full overhaul or dry fill quantity, meaning the lower value generally applies to a fluid exchange and the upper value to a complete transmission rebuild or initial fill.
  • Under normal use conditions, the 2021-2024 NLR87 and NNR87 configurations specify a fluid check interval of 60,000 km, with a full fluid change required at 100,000 km or 60 months, whichever comes first, introducing a time-based limit alongside the distance-based one.
  • The 60-month time limit tied to the 100,000 km normal-use change interval means that calendar age alone can trigger a fluid change before the distance threshold is reached, which is relevant for vehicles operating in low-mileage or infrequent-use conditions.
  • Under severe use conditions, the fluid check interval shortens to 40,000 km for both the 2021-2024 and 2024 starting year NLR87 and NNR87 configurations, reflecting the increased stress placed on transmission fluid under demanding operating environments.
  • The 2024 starting year configuration maintains the same normal-use change interval of 100,000 km or 60 months and the same severe-use check interval of 40,000 km as the 2021-2024 configuration, with the only specification difference being the adjusted lower capacity bound of 9.3 liters versus 9.2 liters.
