Jaguar XJ-S (EU)
Automatic transmission fluid capacity & service interval
Jaguar XJ-S (EU) automatic transmission fluid capacity is 9,1 liters. Service intervals include checks at 5000 km and 10000 km/6 months, with a change interval of 50000 km. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Jaguar XJ-S (EU) V12 carries a 9.1-liter automatic transmission fluid capacity, a figure associated with a complete overhaul or dry fill rather than a routine service top-up.
- For the XJ-S V12 covering model years 1975-1981, the specification labels the 9.1-liter figure explicitly as a complete fill, and the only service action listed is a fluid level check at every 5,000 km intervals under normal use conditions.
- No fluid change interval appears in the 1975-1981 V12 row, meaning the specification for that configuration addresses only the check interval and the complete capacity figure.
- The XJ-S V12 HE, spanning 1981-1991, shares the same 9.1-liter capacity but introduces a more structured service schedule, pairing a check interval with a defined change interval.
- Under normal use conditions, the V12 HE specification calls for a fluid level check every 10,000 km or every 6 months, whichever comes first, reflecting a time-based threshold alongside the distance-based one.
- The V12 HE fluid change interval is set at 50,000 km under normal use, a figure that represents the full drain-and-refill cycle rather than the more frequent level checks.
- Comparing the two configurations, the check interval doubles from 5,000 km on the earlier V12 to 10,000 km on the V12 HE, a difference that runs alongside the introduction of the High Efficiency engine variant in 1981.
