Jaguar XJS, XJ27 (EU)
Automatic transmission fluid capacity & service interval
Jaguar XJS and XJ27 (EU) models require automatic transmission fluid with a capacity range of 4 to 7,3 liters. Service intervals occur every 48000 km or 24 months. The data covers 4 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Jaguar XJS carries two distinct automatic transmission fluid capacities depending on engine configuration: 4.0-liter variants take 4 liters, while 6.0 V12 variants take 7.3 liters.
- A 7.3-liter fill volume on the 6.0 V12 is notably large for an automatic transmission service fill, reflecting the greater fluid volume demands of the transmission paired with a twelve-cylinder drivetrain.
- The 4.0-liter engine variants across both 1991-1994 and 1995-1997 share an identical 4-liter capacity, indicating no change in transmission fluid volume between those two production periods.
- The 6.0 V12 likewise holds the same 7.3-liter capacity across 1991-1994 and 1995-1997, meaning the transmission fluid volume specification remained unchanged across the full 1991-1997 span for that engine.
- All four configurations share a uniform service interval of 48,000 km or 24 months, whichever comes first, applied under normal use conditions.
- The 24-month time limit alongside the 48,000 km distance interval means fluid age alone can trigger a service requirement, independent of mileage accumulation.
- All intervals are specified for normal use conditions, meaning the 48,000 km / 24-month schedule applies to standard operating circumstances rather than demanding or high-stress driving environments.
