Jeep Wagoneer, SJ (EU)

Automatic transmission fluid capacity & service interval

Jeep Wagoneer, SJ (EU) automatic transmission fluid capacity ranges from 3,8 to 8 liters. Service intervals require a change every 24000 km. The data covers 4 configurations.

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

Additional Notes

  • The Jeep Wagoneer SJ (EU) automatic transmission fluid specifications cover two distinct capacity figures for each configuration: a dry fill value and a service fill value. Dry fill represents the total fluid volume required when filling a completely empty transmission, such as after a full rebuild or replacement, while service fill reflects the smaller volume needed when draining and refilling during routine maintenance.
  • The 2.1L TD B EFI (1985-1986) and the 2.8L W 2BBL (1983-1986) share identical capacity figures, with a dry fill of 7.5 liters and a service fill of 3.8 liters. The service fill is roughly half the dry fill, which is consistent with automatic transmissions that retain fluid in the torque converter during a standard drain.
  • The 2.5L H EFI (1986-1988) appears in two separate specification entries with differing values. One entry lists a service fill of 3.8 liters and a dry fill of 7.5 liters, while the second entry lists a service fill of 4 liters and a dry fill of 8 liters. The second set of figures is approximately 6 percent higher across both capacities.
  • The presence of two distinct capacity sets for the same 2.5L H EFI engine suggests the possibility of more than one transmission unit being fitted to that configuration across the 1986-1988 production span, with each unit carrying a slightly different fluid volume requirement.
  • All four specification rows share a uniform change interval of 24,000 km under normal use conditions. No variation in service interval exists across the different engine types or model years represented in the specifications.
  • The 2.8L W 2BBL covers the widest model year span among the listed configurations, running from 1983-1986, and carries the same 7.5-liter dry fill and 3.8-liter service fill as the later 2.1L TD unit introduced in 1985.
