Jeep Wagoneer, SJ (EU)

Additional Notes

• The Jeep Wagoneer SJ (EU) transfer case fluid specifications cover three engine variants across the 1983-1988 model range: the 2.1L TD, the 2.5L H EFI, and the 2.8L W 2BBL.
• All transfer case fluid change intervals across every listed engine variant are set at 24,000 km under normal use conditions, with no variation between engine types.
• The 2.1L TD B EFI (1985-1986) and the 2.8L W 2BBL (1983-1986) share an identical pair of transfer case capacity figures: 2.1 liters and 3.3 liters. The presence of two distinct values for the same engine suggests two different transfer case units were fitted to each of those engine configurations.
• A 3.3-liter transfer case capacity is the largest figure listed across all specifications. A fill volume of that size is consistent with a larger or more complex transfer case assembly requiring a substantial fluid charge to maintain adequate lubrication across all internal components.
• The 2.5L H EFI (1986-1988) has the widest spread of transfer case capacity values among the listed variants, with figures of 1.0, 1.4, and 1.6 liters recorded. The 1.6-liter figure appears twice, indicating at least two separate transfer case units share that capacity within the same engine configuration.
• The 1.0-liter capacity listed for the 2.5L H EFI is the smallest transfer case fluid volume in the entire dataset. A fill volume that low points to a notably compact transfer case unit relative to those paired with the 2.1L TD and 2.8L W 2BBL engines.
• The 2.5L H EFI variant entered production in 1986, the same final year of the 2.1L TD and 2.8L W 2BBL variants, meaning all three engine configurations were present simultaneously during the 1986 model year.
