Audi 100, 43 (EU)

Automatic transmission fluid capacity & service interval

Audi 100, 43 (EU) automatic transmission fluid capacity ranges from 3 to 6 liters. Service intervals include checks at 10000 km and 15000 km, with fluid changes at 30000 km and 45000 km. The data covers 6 configurations.

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

Additional Notes

  • Across all three variants of the Audi 100, 43 (EU) covered here — the 1.6, 2.0, and 5E — the automatic transmission dry fill capacity is 6 liters, a figure that represents the total fluid volume required when filling a fully drained or rebuilt unit from empty.
  • The service fill capacity of 3 liters applies to all listed variants and reflects the partial volume exchanged during a routine fluid change, where residual fluid remains in the torque converter and passages after draining.
  • The 6-liter dry fill versus 3-liter service fill relationship means that a routine service interval change replaces approximately half the total fluid volume in the transmission.
  • Under normal use conditions, the 1.6 and 2.0 engine variants share a fluid check interval of 15,000 km and a change interval of 45,000 km, identical figures that also apply to the five-cylinder 5E variant introduced in 1977.
  • Under severe use conditions, the check interval shortens to 10,000 km and the change interval to 30,000 km across all three variants, representing a one-third reduction compared to normal use intervals.
  • The 5E variant entered the lineup in 1977, two years after the 1.6 and 2.0 variants began in 1976, yet carries the same automatic transmission fluid capacities and interval structure as the earlier engine configurations.
  • The 45,000 km normal-use change interval and the 30,000 km severe-use change interval both apply uniformly regardless of engine displacement, indicating the interval structure was tied to the transmission unit rather than engine output.
