Frequently Asked Questions
Does this manual cover the XJ-C coupe body style?
Yes. The XJ-C (also badged XJ4.2C) two-door coupe is included alongside the four-door saloon. All body, interior, and chassis procedures apply to both body styles, and where differences exist between coupe and saloon configurations they are identified separately within the relevant sections.
Which automatic transmission is fitted to the XJ6?
XJ6 models equipped with automatic transmission used the Borg-Warner Model 12 three-speed unit. The manual includes complete service and rebuild procedures for this gearbox, covering selector adjustments, fluid specifications, band adjustments, and full disassembly torque data.
Are full wiring diagrams included for the Lucas electrical system?
Yes. Complete circuit diagrams covering all model years from 1973 to 1979 are included. These diagrams detail the Lucas ignition, charging, lighting, and accessory circuits with wire color codes, connector locations, and component ground points clearly identified — essential for diagnosing the electrical faults these cars are known for.
What format is the manual?
The manual is delivered as a PDF file, compatible with Windows, Mac, Linux, Android, and iOS devices. The text is fully searchable, and individual pages or complete sections can be printed for use in the workshop.
