DKW - Auto Union Junior / F11 / F12

Manual transmission fluid capacity & service interval

DKW - Auto Union Junior / F11 / F12 requires 1,75 liters of manual transmission fluid. Service intervals include checks at 7500 km or 10000 km/6 months and changes at 30000 km or 30000 km/18 months. The data covers 6 configurations.

Additional Notes

  • Across all six configurations of the DKW - Auto Union Junior / F11 / F12, the manual transaxle fluid capacity is uniformly 1.75 liters. A transaxle combines the transmission and final drive into a single housing, so this figure represents the total fill volume for that integrated unit rather than a standalone gearbox.
  • The Junior (1959-1962) and Junior de Luxe (1961-1963) share a check interval of 7500 km with no time-based component, while the F11 and F12 variants specify a check interval of 10000 km or 6 months, whichever comes first. The addition of a calendar-based threshold in the later models reflects a dual-condition approach where elapsed time triggers a check even when mileage accumulation is low.
  • The fluid change interval for the Junior and Junior de Luxe is stated as 30000 km with no accompanying time limit, whereas the F11 and all F12 variants pair the same 30000 km distance with an 18-month maximum. Under normal use conditions, the 18-month ceiling on the F-series means a time-triggered change is possible before the mileage threshold is reached.
  • The F12 was produced in two power outputs: 29 kW and 33 kW, both covering 1963-1965. Despite the difference in engine output, both share identical transaxle fluid capacity, check, and change intervals, indicating the same transmission unit was used across both F12 engine variants.
  • The F12 Roadster carries a single production year of 1964, yet retains the same 1.75-liter transaxle capacity and the 10000 km / 6-month check with 30000 km / 18-month change schedule applied to the rest of the F12 range.
  • The overlap between the Junior de Luxe (1961-1963) and the F11 / F12 (1963-1965) means that during 1963, both the older kilometer-only service schedule and the newer dual kilometer-and-time schedule were in use simultaneously across the model family.
