Wolseley 6/99, 6/110

Manual transmission fluid capacity & service interval

Wolseley 6/99 and 6/110 models require manual transmission fluid with a capacity of 3 liters. Service intervals include checks at 1500 km and changes at 800 km or 9000 km. The data covers 4 configurations.

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

Additional Notes

  • The Wolseley 6/99 and 6/110 share an identical manual transmission fluid capacity of 3 liters, which represents the service fill volume for the gearbox.
  • Under normal use conditions, the manual transmission fluid change interval is set at 9000 km for both the 6/99 (1959-1961) and the 6/110 (1961-1968).
  • A fluid level check is specified at 1500 km under normal use conditions, applying equally across both model variants.
  • An initial service change interval of 800 km is listed for both variants, reflecting the early drain recommendation tied to a newly run-in gearbox where metal particles and contaminants accumulate rapidly in fresh fluid.
  • No capacity difference exists between the initial service and normal use entries for either variant, with both recording 3 liters regardless of the service stage.
  • The 6/99 covered the 1959-1961 period, while the 6/110 ran from 1961-1968, meaning the two models shared a production overlap year in 1961 yet carried identical manual transmission fluid specifications throughout.
