Lexus LS, XF20 (EU)

Automatic transmission fluid capacity & service interval

Lexus LS, XF20 (EU) automatic transmission fluid capacity ranges from 1,8 to 1,9 liters. Service intervals include checking every 15000 km or 12 months and changing every 60000 km or 48 months. The data covers 2 configurations.

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

Additional Notes

  • The Lexus LS, XF20 (EU) automatic transmission fluid capacity differs between the two generation variants covered in the specifications. The 1995-1997 LS 400 carries a service fill capacity of 1.9 liters, while the 1997-2000 variant is specified at 1.8 liters.
  • A 1.9-liter or 1.8-liter figure in an automatic transmission service context represents a partial drain-and-fill quantity rather than a full overhaul or dry-fill volume, as a complete transmission flush would typically require a significantly larger amount of fluid.
  • Both the 1995-1997 and 1997-2000 LS 400 configurations share an identical check interval of 15,000 km or 12 months, whichever comes first, under normal use conditions.
  • The change interval for automatic transmission fluid on both variants is set at 60,000 km or 48 months under normal use conditions, reflecting a relatively extended service cycle consistent with sealed or semi-sealed automatic transmission designs of that era.
  • The 0.1-liter difference in service fill capacity between the 1995-1997 and 1997-2000 LS 400 variants points to a mechanical revision in the transmission assembly between those production periods, even though the check and change intervals remain unchanged across both.
