Additional Notes

  • Across all three configurations covered in the 2005-2008 Audi A4, S4, RS 4 8E/B7 (USA) automatic transmission specifications, the fluid capacity is listed at 9.8 liters as an initial fill figure, meaning the value reflects the amount of fluid required when filling a dry or freshly rebuilt unit rather than a partial top-up during routine service.
  • The A4 2.0 T quattro (147 kW) carries a transaxle designation for its automatic unit, distinguishing it from the transmission designation applied to the A4 3.2 quattro (188 kW) and S4 4.2 V8 quattro (253 kW) entries, which reflects a difference in how the drivetrain assembly is classified between those configurations.
  • Under normal use conditions, all three configurations share a check interval of 20,000 miles or 12 months, whichever comes first, applying equally to the 2.0 T, 3.2, and 4.2 V8 variants across the 2005-2008 model years.
  • A separate first check only interval of 15,000 miles or 12 months is specified for each of the three configurations, tied directly to the same 9.8-liter initial fill capacity, indicating an earlier inspection point following a fresh fluid fill before the standard 20,000-mile normal interval takes effect.
  • The S4 4.2 V8 quattro (253 kW), despite producing significantly more power than the A4 2.0 T quattro (147 kW), shares an identical 9.8-liter initial fill capacity and the same check intervals under both normal and first check only conditions.
  • The 9.8-liter capacity figure appearing consistently across the 2.0 T, 3.2, and 4.2 V8 configurations suggests a common automatic transmission platform was used across the 2005-2008 A4 and S4 lineup in the US market specification.
