Additional Notes

  • The Lexus LS 400 automatic transmission service fill capacity is 1.9 liters across all listed configurations for 1995-2000, covering both USA and Canadian market variants. A service fill figure reflects the amount of fluid added during a routine partial drain-and-fill, not a complete transmission overhaul refill.
  • For the LS 400 (USA) under normal use conditions spanning 1995-2000, the specified interval is a fluid check at 15,000 miles or 24 months, whichever comes first. No fluid change interval is listed under normal use for the USA market.
  • Under severe use conditions for the LS 400 (USA) across 1995-2000, the same 15,000-mile or 24-month interval applies, but the action specified is a fluid change rather than a check. Severe use conditions typically involve more demanding operating environments such as frequent towing, stop-and-go traffic, or extreme temperatures, which accelerate fluid degradation.
  • The 1998 LS 400 (USA) carries the same interval structure as the 1995-1997 entries, with a normal-use check and a severe-use change both set at 15,000 miles or 24 months. No specification differences separate the 1998 model year from the surrounding years in the USA market data.
  • The Canadian market LS 400 for 1999-2000 specifies a check interval of 16,000 km alongside a change interval of 96,000 km under normal use conditions. The 96,000 km change interval represents a considerably extended service period compared to the mileage-based severe-use change interval listed for the USA market.
  • The Canadian specification expresses intervals in kilometers, while all USA market entries use miles and a time-based component of 24 months. The 16,000 km check interval for the Canadian LS 400 (1999-2000) is roughly equivalent to the 15,000-mile USA check interval when converted, reflecting regional measurement standards rather than a fundamental difference in service frequency.
