Leyland DAF 400

Manual transmission fluid capacity & service interval

Leyland DAF 400 manual transmission fluid capacity ranges from 1,6 to 2 liters. Service intervals require checks every 20000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The Leyland DAF 400 V400 2.0 carries a manual transmission fluid capacity of 2 liters, which is the larger of the two distinct capacity figures present across the 400 range's manual transmission specifications.
  • The V400 2.5 D and V400 2.5 TD both share a manual transmission fluid capacity of 1.6 liters, placing both diesel variants below the 2.0-liter petrol engine's transmission fill volume.
  • A capacity of 1.6 liters in a manual transmission context typically represents a service fill level, meaning the amount required to bring fluid up to the correct operating level during routine maintenance rather than a full drain-and-refill overhaul quantity.
  • The V400 2.0 specification includes a defined check interval of every 20,000 km or 12 months, whichever comes first, applied under normal use conditions.
  • The 20,000 km or 12-month interval on the V400 2.0 reflects a time-based ceiling alongside a distance threshold, meaning calendar time alone can trigger a fluid check even when mileage accumulation is low.
  • The V400 2.5 D and V400 2.5 TD rows carry no stated check or change interval in the specifications, in contrast to the interval entry present for the V400 2.0.
  • All three configurations carry a normal use condition designation, meaning none of the listed specifications are tied to severe-duty or first-change-only service scenarios.
  • The capacity difference between the V400 2.0 at 2 liters and the two 2.5-displacement diesel variants at 1.6 liters each suggests the petrol and diesel engines were paired with mechanically distinct manual transmission units across the 1989-1996 production span.
