Additional Notes

  • The Land Rover Discovery 1 LJ (USA) transfer case holds 2.3 liters of fluid across both the 3.9 V8i (1993-1995) and 4.0 V8i (1995-1998) engine configurations, indicating a service fill volume rather than a full overhaul drain-and-refill figure, which would typically account for residual fluid left in the unit.
  • A 2.3-liter capacity places the transfer case in a moderate range for a part-time four-wheel-drive unit of this era, consistent with the LT230 transfer box fitted to the Discovery 1 platform.
  • The 3.9 V8i and 4.0 V8i share an identical 2.3-liter transfer case capacity, meaning no adjustment to fluid quantity is required when servicing either engine variant.
  • Both configurations carry a 30,000-mile change interval under normal use conditions, which reflects standard on-road driving without the added stress of frequent off-road operation, towing, or extreme temperature exposure.
  • The 30,000-mile interval applies uniformly across the 1993-1998 model span covered by both rows, with no variation between the earlier 3.9 V8i and the later 4.0 V8i in terms of service frequency.
