Audi A4, S4, 8D / B5 (USA)

Automatic transmission fluid capacity & service interval

Audi A4, S4, 8D / B5 (USA) automatic transmission fluid capacities range from 2,6 to 9 liters. Service intervals include checks at 10000 miles or 12 months and 15000 miles or 12 months. The data covers 7 configurations.

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

Additional Notes

  • Across all seven configurations in the Audi A4 and S4 (8D / B5) USA lineup, the automatic transmission initial fill capacity is 9 liters. This figure represents the total fluid volume required when filling a dry transmission from scratch, such as during a full overhaul or replacement.
  • The 1.8 T 5V (110 kW) configurations, both standard and quattro, list a separate service fill capacity of 2.6 liters. A service fill reflects the amount of fluid displaced during a routine drain-and-refill procedure, which is always less than the initial fill because residual fluid remains in the torque converter and passages.
  • The 2.8 V6 configurations and the S4 2.7 Bi-turbo V6 quattro list a refill capacity of 2.8 liters rather than a service fill. The slightly higher refill figure compared to the 1.8 T's 2.6-liter service fill reflects the different transmission units fitted to the larger-displacement engines.
  • The 2.8 V6 and S4 2.7 Bi-turbo V6 quattro rows present the 9-liter initial fill value under a "filter capacity" label, whereas the 1.8 T rows present the same 9-liter figure simply as an initial fill. Both describe the same type of measurement — total system capacity at first fill — but the labeling differs between transmission families.
  • The check interval for the 1.8 T 5V configurations is 10,000 miles or 12 months under normal use conditions, whichever comes first. This is shorter by 5,000 miles than the interval specified for the V6 and S4 configurations.
  • The 2.8 V6 configurations across all power outputs and drivetrain variants, along with the S4 2.7 Bi-turbo V6 quattro, share a check interval of 15,000 miles or 12 months under normal use conditions. The 15,000-mile figure applies equally to the 128 kW and 142 kW versions of the 2.8 V6, indicating no interval difference between the two power outputs.
  • The 2.8 V6 (128 kW) was produced for the 1996-1997 model years, while the higher-output 142 kW version covers 1997-2001. Both share identical automatic transmission fluid capacities and check intervals, meaning the power increase between generations had no effect on the transmission service specifications.
  • The S4 2.7 Bi-turbo V6 quattro (187 kW), produced from 1999, carries the same 2.8-liter refill and 9-liter initial fill figures as the naturally aspirated 2.8 V6 configurations, despite the substantially higher power output of the forced-induction engine.
