Alfa Romeo 159, 939 (EU)

Automatic transmission fluid capacity & service interval

Alfa Romeo 159, 939 (EU) automatic transmission fluid capacity ranges from 3,3 to 6,1 liters. Service intervals require a check every 30000 km. The data covers 5 configurations.

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

Additional Notes

  • The Alfa Romeo 159 939 (EU) automatic transmission is a transaxle unit, meaning the transmission and final drive are housed together, which accounts for the relatively high dry fill capacity recorded across all listed configurations.
  • A dry fill capacity of 6.1 liters applies to every listed engine variant from 2005-2010, reflecting the total fluid volume required when the transaxle is completely empty, such as after a full rebuild or replacement.
  • The service fill capacity of 3.3 liters is roughly half the dry fill figure, representing the amount of fluid displaced during a routine drain-and-fill procedure where residual fluid remains in the torque converter and passages.
  • The 1.9 JTDm 16V in both its 100 kW and 110 kW outputs shares identical automatic transaxle fluid capacities and check intervals across the full 2005-2010 span, indicating the output difference between the two variants does not affect transmission fluid specifications.
  • The 2.4 JTDm 20V appears in two distinct entries: a 2005-2007 configuration and a 2007-2010 Qtronic-designated configuration, both carrying the same 6.1-liter dry fill and 3.3-liter service fill values.
  • The Qtronic designation on the 2.4 JTDm 20V from 2007-2010 refers to a specific automated manual or sequential automatic gearbox variant, yet the fluid capacity figures remain consistent with the earlier 2.4 JTDm 20V entry.
  • The 3.2 JTS Q4, the only petrol all-wheel-drive variant in the listed data, carries the same 6.1-liter dry fill and 3.3-liter service fill as the diesel front-wheel-drive configurations across 2005-2010.
  • A fluid check interval of 30,000 km under normal use conditions is specified uniformly across all five configurations, with no separate severe-use interval listed in the data.
