Audi 100, F104 (EU)

Automatic transmission fluid capacity & service interval

Audi 100, F104 (EU) models utilize automatic transmission fluid with capacities ranging from 3 to 6 liters. Service intervals consist of a 10000 km check and a 30000 km change. The data covers 3 configurations.

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

Additional Notes

  • The Audi 100, F104 (EU) 100 Coupé S (1971-1976) automatic transmission carries a dry fill capacity of 6 liters, which represents the total fluid volume required when filling a completely drained or newly assembled unit with no residual fluid present.
  • The service fill capacity for the 100 Coupé S (1971-1976) is 3 liters, reflecting the reduced volume needed during a routine fluid change where a portion of fluid remains in the torque converter and passages after draining.
  • The 100 GL (1970-1976) automatic transmission lists a dry fill capacity of 3 liters and a service fill capacity of 6 liters, which is an inversion of the pattern seen in the other two variants within the same specification set.
  • The 100 LS (74 kW) (1968-1971) shares the same 6-liter dry fill and 3-liter service fill figures as the 100 Coupé S, placing both variants in contrast with the 100 GL capacity values.
  • All three variants specify a fluid check interval of 10,000 km under normal use conditions, indicating a periodic inspection point separate from the full change interval.
  • The change interval across all three variants is set at 30,000 km under normal use conditions, applying uniformly regardless of engine output or body configuration within the F104 generation.
