Additional Notes

  • The Jaguar XJ X308 (USA) automatic transmission fluid capacity differs between the XJ8 4.0 and the XJR, with the XJ8 4.0 requiring 10 liters and the XJR requiring 9.5 liters.
  • The XJ8 4.0 transmission capacity of 10 liters applies across the full 1999-2003 model year span covered in the specifications.
  • The XJR specification covers 2001-2003, a narrower range than the XJ8 4.0, and carries a slightly lower fluid capacity of 9.5 liters.
  • Both configurations list a single capacity figure under normal use conditions, meaning the stated volumes reflect standard service fill rather than a dry or overhaul fill scenario.
  • A 0.5-liter difference between the XJ8 4.0 and XJR capacities indicates a measurable variation in transmission sump or torque converter volume between the two engine configurations.
  • Both the XJ8 4.0 and XJR entries are designated for the automatic transmission specifically, distinguishing the fluid system from any other drivetrain components.
