Additional Notes

  • Across all XJ8 variants in the Jaguar XJ X308 (EU) range, the automatic transmission fluid capacity is 10 liters, a figure consistent across both the 3.2 and 4.0 engine displacements and across both the 1997-2001 and 2001-2003 production periods.
  • The XJR carries a slightly lower automatic transmission fluid capacity of 9.5 liters, compared to the 10-liter figure shared by all XJ8 configurations. This 0.5-liter difference applies to both the 1997-2001 and 2001-2003 XJR variants.
  • Under normal use conditions, the check interval for automatic transmission fluid across all configurations is 16,000 km or 12 months, whichever comes first. Both the distance and time thresholds apply together as a combined trigger.
  • Under severe use conditions, the time-based check interval shortens to every 6 months for all configurations. No kilometer-based distance threshold is listed alongside the severe-use interval.
  • The halving of the check interval from 12 months to 6 months under severe conditions applies uniformly across all variants, including both XJ8 engine sizes and the XJR, regardless of production period.
  • The capacity figures remain unchanged between the 1997-2001 and 2001-2003 production periods for each respective variant. The 3.2 and 4.0 XJ8 models retain 10 liters, and the XJR retains 9.5 liters across both periods.
  • A 10-liter automatic transmission fluid capacity is a relatively large service fill, indicating a transmission with a substantial fluid sump or an integrated torque converter volume included in the total figure.
