Land Rover Forward Control, 110 (EU)

Manual transmission fluid capacity & service interval

Land Rover Forward Control and 110 (EU) models require manual transmission fluid with a capacity of 1,5 liters. Service intervals include changes at 2500 km/60 hours, 1 month, and 15000 km/360 hours, plus checks at 5000 km/120 hours. The data covers 9 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Land Rover Forward Control manual transmission capacity is 1.5 liters across all three variants covered by the specifications, namely the 109 (1961-1971), the Forward Control 6 110 (1966-1972), and the Forward Control Diesel 110 (1966-1972).
  • A 1.5-liter figure for a manual transmission represents a service fill quantity, meaning the amount of fluid required during a routine drain-and-refill procedure rather than a full overhaul capacity that would account for additional fluid retained in ancillary components.
  • An initial service interval of 2,500 km or 60 hours applies to all three variants, with a fluid change required at whichever threshold is reached first. An initial service interval exists to flush out metal particles and contaminants generated during the mechanical break-in period of a new or rebuilt transmission.
  • Under severe use conditions, the change interval for all three variants is defined solely in calendar time at 1 month, with no distance or hour-based threshold listed alongside it.
  • Under normal road conditions, a fluid check is specified at 5,000 km or 120 hours, while the full fluid change interval extends to 15,000 km or 360 hours. The check interval at roughly one-third of the change interval allows for monitoring fluid level and condition before the full service is due.
  • The 360-hour change threshold under normal road conditions reflects a time-based service criterion independent of distance, which is relevant for vehicles operating at low speeds or in stationary power-take-off applications where hours accumulate faster than kilometers.
  • The petrol-engined Forward Control 6 110 and the Forward Control Diesel 110 share identical manual transmission capacities and service intervals across all three use conditions, despite the differing engine types.
  • The Forward Control 109 covers model years 1961-1971, while the 110 variants begin in 1966, meaning the 109 predates the 110 variants by five years according to the specifications.
