Additional Notes
- Across the Land Rover Series III 88/109 lineup, the transfer case fluid capacity for the four-cylinder petrol and diesel variants — both 88 and 109 wheelbase — is 2.5 liters. This figure applies to the transferbox equipped with a low range transmission.
- The Series III-V8, 109 carries a notably higher transfer case fluid capacity of 3.1 liters. The absence of a low range transmission note in the V8 specification distinguishes the unit from the four-cylinder and six-cylinder configurations, which all reference a transferbox with low range transmission.
- The six-cylinder Series III-6, 109 covers the 1971-1979 model years and shares the 2.5-liter transfer case capacity and low range transmission designation with the four-cylinder variants, despite the difference in engine configuration.
- The Series III-V8, 109 spans 1979-1983, a narrower production window compared to the 1971-1985 range of the four-cylinder petrol and diesel variants.
- All six configurations share the same fluid check interval of every 10,000 km or 6 months, whichever comes first, under normal road conditions. The time-based component of the interval means seasonal or low-mileage use still triggers a check within half a year.
- The fluid change interval is consistent across all listed configurations at 40,000 km or 24 months under normal road conditions. The 24-month time limit means a change is due every two years regardless of distance traveled, which is relevant for vehicles used infrequently.
- The 2.5-liter capacity applies uniformly to the diesel 88, diesel 109, petrol 88, petrol 109, and six-cylinder 109 variants. A transfer case holding 2.5 liters is a relatively substantial volume, reflecting the robust, truck-derived nature of the Series III unit.
- All specifications are stated for normal road conditions. A transfer case with a low range gear set, as noted across the majority of configurations, is designed for off-road and low-speed high-torque use, though the service intervals here are tied specifically to normal road operation.
