Additional Notes

  • The Lexus LS 400 (USA) 1990 model year carries a dry fill capacity of 7.2 liters for the automatic transmission, which represents the total fluid volume required when filling a completely drained or rebuilt unit from empty.
  • From 1991 onward, the dry fill capacity increased to 8.2 liters for 1991-1992 and then to 8.3 liters for 1993-1994, marking a notable step up from the 1990 figure of 7.2 liters.
  • The service fill capacity for the 1990 model year is 1.6 liters, reflecting only the partial volume exchanged during a routine fluid service rather than a full drain and refill.
  • Starting with the 1991-1992 model years, the service fill capacity rose to 1.9 liters, a value that remained consistent through 1994, even as the dry fill capacity saw a minor adjustment between 1992 and 1993.
  • Under normal use conditions for the 1990 model year, the specified interval is a fluid check at 15,000 miles or 24 months, meaning no fluid change is prescribed at that interval in normal operation.
  • Under severe use conditions for the 1990 model year, the same 15,000-mile or 24-month interval is specified as a fluid change rather than a check, indicating a more demanding service action at an identical mileage and time threshold.
  • The normal and severe use interval structure of 15,000 miles or 24 months, with a check under normal conditions and a change under severe conditions, applies consistently across all model years from 1990 through 1994.
  • The dry fill capacity of 8.3 liters recorded for 1993 represents the highest total transmission fluid volume across the entire 1990-1994 span, shared identically with the 1994 model year.
