Iveco Daily 42

Automatic transmission fluid capacity & service interval

Iveco Daily 42 uses automatic transmission fluid with a capacity range of 4 to 9,6 liters. Service intervals include 200000 km or 350000 km/120 months. The data covers 5 configurations.

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

Additional Notes

  • The dry fill capacity represents the total fluid volume required when filling a completely empty transmission, such as after a full overhaul or unit replacement. The Iveco Daily 42 S 14, S 16 (standard), S 18, and S 21 variants all share a dry fill capacity of 9.5 liters, while the Daily 42 S 16 3.0 requires a slightly higher 9.6 liters.
  • The service fill capacity of 4-5 liters applies across all five variants and reflects the volume needed during a routine fluid change, where residual fluid remains in the torque converter and transmission passages. A range rather than a fixed figure is typical because the exact amount retained varies depending on drain time and transmission temperature.
  • The gap between the dry fill and service fill figures, roughly 4.5 to 5.5 liters, represents the fluid that stays within the transmission circuit during a standard drain procedure and is not recovered without a full disassembly or flush.
  • All specifications are listed under normal use conditions, meaning the intervals apply to standard operating environments rather than elevated-stress or high-cycle applications.
  • The Daily 42 S 14, S 16 (standard), S 18, and S 21 share a fluid change interval of 200,000 km, which is a common long-life interval for modern sealed automatic transmissions in commercial vehicle applications.
  • The Daily 42 S 16 3.0 carries a notably extended change interval of 350,000 km or 120 months, whichever comes first. The addition of a time-based limit of 120 months (10 years) alongside the distance figure means fluid degradation over time is also a factor, not only mileage accumulation.
  • The 350,000 km interval on the Daily 42 S 16 3.0 is 75% longer than the 200,000 km interval specified for the other variants, a difference that reflects either a distinct transmission unit, fluid specification, or engineering assessment tied to the 3.0-liter engine pairing.
