Isuzu Midi Van

Manual transmission fluid capacity & service interval

Isuzu Midi Van manual transmission fluid capacity is 1,55 liters. Service intervals include checks every 10000 km or 6 months and changes every 40000 km or 24 months. The data covers 2 configurations.

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

Additional Notes

  • Both the 1.8 and 2.0 D variants of the Isuzu Midi Van (WFR) share an identical manual transmission fluid capacity of 1.55 liters, which is a relatively modest fill volume consistent with compact light-commercial gearbox designs of the mid-1980s.
  • The 1.55-liter figure represents a service fill capacity, meaning the quantity of fluid the transmission holds under normal operating conditions rather than a full overhaul or dry-fill measurement.
  • Under normal use conditions, the check interval is set at 10,000 km or 6 months, whichever comes first, indicating a relatively frequent inspection schedule relative to the change interval.
  • The fluid change interval under normal use is 40,000 km or 24 months, placing a full drain-and-refill cycle at roughly four times the frequency of the check interval in distance terms.
  • The 1985-1988 petrol 1.8 and diesel 2.0 D configurations carry no differentiation in either capacity or service intervals, meaning the manual transmission specifications are uniform across both engine types for the WFR body.
