Wolseley 6/99, 6/110

Automatic transmission fluid capacity & service interval

Wolseley 6/99 and 6/110 models require automatic transmission fluid with a capacity of 8,52 liters. Service intervals include checks at 800 km and 4800 km, with a change interval of 38400 km. The data covers 4 configurations.

Additional Notes

  • Both the Wolseley 6/99 and 6/110 share an identical automatic transmission fluid capacity of 8.52 liters, a figure that applies uniformly across all four specification rows regardless of model year or use condition.
  • An 8.52-liter automatic transmission capacity is a relatively substantial fill volume, consistent with the larger, multi-component fluid circuits found in period automatic gearboxes, which typically required fluid to service not only the gearbox internals but also the torque converter.
  • The 6/99 covered the 1959-1961 model years, while the 6/110 spanned 1961-1968, meaning the two models overlapped at the 1961 year point before the 6/99 was succeeded.
  • Under normal use conditions, both models share a check interval of 4,800 km and a change interval of 38,400 km for the automatic transmission fluid.
  • A separate initial service check interval of 800 km is specified for both the 6/99 and 6/110, tied to the same 8.52-liter capacity, reflecting the practice of inspecting fluid condition shortly after a new or freshly serviced transmission has been run in.
  • The 800 km initial service check interval is notably shorter than the 4,800 km normal check interval, a gap that reflects the early break-in period during which transmission fluid can accumulate contaminants or show level changes more rapidly than in steady-state operation.
  • No change interval is listed under the initial service rows for either model, meaning the 38,400 km drain-and-fill figure applies exclusively within the normal use condition entries.
