Xj Series Standard Transmission:
Typically a 3-speed automatic (GM TH400) for early V12 models, and a 4-speed automatic (ZF 4HP22) for I6 and later V12 models.
Xjs Optional Transmission:
Manual transmissions (e.g., 4-speed or 5-speed Getrag) were available on some XJS models.
Automatic Transmission Features:
Electronic control units (ECUs) for shift timing and mode selection (e.g., Sport/Economy modes on ZF transmissions).
Oil Change Interval:
Typically every 3,000-6,000 miles (5,000-10,000 km) or 6-12 months, depending on driving conditions and oil type used. Consult manual for specifics.
Spark Plug Replacement:
Varies by engine type and plug material (e.g., copper, platinum). Intervals could range from 12,000 to 30,000 miles.
Engine Oil Specification:
API SG/SH rated, viscosity typically 10W-30 or 10W-40. V12 engines may have specific recommendations for high-performance oils. Consult manual for exact specs and capacities.
Transmission Fluid Specification:
For ZF 4HP22: DEXRON II or equivalent. For GM TH400: DEXRON II or equivalent. Always check manual for precise specification and capacity.
Coolant Specification:
Ethylene glycol-based coolant with appropriate corrosion inhibitors. Typically a 50/50 mix with distilled water. Consult manual for specific type and capacity.
Xj40 Common Issues:
Electrical gremlins (especially related to the JEC/engine management computer), corrosion, aging suspension bushings, potential head gasket issues on early AJ6 engines, ABS system faults.
Xjs Common Issues:
Rust in sills, wheel arches, and around windows; carburetor issues (on earlier models); aging fuel lines and cooling system components; ABS sensor faults; potential gearbox issues on high-mileage examples.
Heritage:
Jaguar's long-standing reputation for luxury, performance, and elegant styling.
Xj40 Development:
The XJ40 (XJ6/XJ12) represented a significant modernization for Jaguar's flagship sedan, moving away from the Series III XJ design. It featured a more contemporary, albeit controversial, exterior and interior design, along with significant mechanical updates.
Xjs Development:
The XJS, initially a grand tourer, evolved through this period with engine upgrades (from the 5.3L V12 to the 6.0L V12) and styling refinements, including the 'facelift' models which added more conventional bumpers and improved aerodynamics.
