Service intervals

The L322 responds dramatically to good servicing, many of its expensive failures trace straight back to skipped maintenance. The factory "lifetime" claims on the gearbox and other fluids should not be taken literally. The intervals below are practical recommendations; confirm the service schedule and fluid specification for the exact car. For the practical jobs to keep on top of between services, see the maintenance guide.

QUICK ANSWER

Service the engine regularly and don't trust 'sealed for life' on the gearbox, change its fluid every ~4 years / 64k km. Use a specialist who knows L322s.

About these figures: the intervals below are PRACTICAL recommendations: they are not the official Land Rover service schedule. Land Rover marketed several of these fluids as "sealed for life". Items marked OEM are manufacturer specifications. Always confirm against the official handbook / RAVE manual for your exact car.

Engine servicing SPECIALIST GUIDE

Item	Interval
Engine oil & filter (petrol)	per schedule; many shorten it
Engine oil & filter (TDV8?TDV8: Land Rover's twin-turbo diesel V8 (3.6, later 4.4), the 'AJD-V8' / 'Lion' engine, prized for huge torque.)	~12,875 km / 12 mo (change early)
Air, fuel, pollen filters	per service schedule
Coolant flush	~95,000 km (limits pipe/seal corrosion)
EGR clean (diesel)	~80,000 km

TIP On the TDV8s, "the engine rewards paranoia", early oil changes and a pre-emptive metal coolant pipe are the cheapest insurance you can buy.

Gearbox & driveline SPECIALIST GUIDE

Item	Interval
Auto gearbox oil + filter	every 4 yrs / 65,000 km (ignore "sealed for life")
Gearbox by ~160,000 km	definitely change oil & filter if not done
Transfer box oil	change periodically; watch for leaks
Front/rear diff oil	change periodically

WHY IT MATTERS A gearbox specification does not establish a failure mileage. A replacement runs €2,500-3,500, enough to write off a cheap car. A €230-460 service is cheap by comparison.

Fluids quick reference OEM SPEC

Component	Fluid
ZF 6-speed auto	ZF Lifeguard 6
ZF 8-speed auto	ZF Lifeguard 8 (not interchangeable)
GM 5L40-E (Td6)	Texamatic 7045E type
Engine oil (TDV8)	Land Rover STJLR.03.5006 spec

Always confirm exact specs in the RAVE workshop manual / handbook for your car.

Diesel-specific notes

Check the water pump is replaced at the cambelt/timing service.
Allow turbos to cool 2-3 min after hard driving before shut-down.
Keep coolant fresh to protect the crossover pipe and seals.

Gearbox fluid procedure (note)

NOTE Use the fluid-level procedure and temperature window specified for the exact gearbox. ZF's filling guidance distinguishes transmission variants and requires the vehicle manufacturer's instructions to be followed; it does not establish a universal ZF/GM temperature range. Use suitable diagnostic equipment and the applicable workshop procedure.
