AMC Eagle

Transfer case fluid capacity & service interval

AMC Eagle transfer case fluid capacity ranges from 1,4 to 3,3 liters. Service intervals include checking at 6000, 8000, or 12000 km, and changing at 20000, 24000, or 48000 km. The data covers 7 configurations.

Additional Notes

  • The AMC Eagle 258 in its 1980 model year carries a transfer case capacity of 1.4 liters, paired with a change interval of 24000 km or 15 months — a slightly longer drain interval than the 20000 km or 13 months specified for the same engine in the 1981-1983 period.
  • For the 151 and 258 engines covering 1981-1983, the transfer case capacity is listed as a range of 1.4 to 2.8 liters. A capacity range of this kind typically reflects variation between different transfer case units that may be installed across production runs or trim configurations within those years.
  • By 1984-1985, both the 151 and 258 engine configurations settle on a fixed transfer case capacity of 2.8 liters, replacing the variable range seen in the 1981-1983 entries. A fixed single value generally indicates a standardized unit across all applicable builds for those years.
  • The 258 engine for 1986-1988 shows a notably larger transfer case capacity of 3.3 liters compared to all earlier entries. A larger fluid capacity often corresponds to a physically larger or redesigned transfer case unit.
  • The 1986-1988 Eagle 258 under normal use conditions has a fluid check interval of 12000 km or 7 months, which is longer than the 8000 km or 5 months specified for all earlier model year entries regardless of engine type.
  • Under severe use conditions, the 1986-1988 Eagle 258 transfer case requires a fluid check every 6000 km or 4 months and a fluid change every 24000 km or 15 months. Under normal use for the same years, the change interval extends to 48000 km or 30 months — a difference of 24000 km between the two use conditions.
  • The 48000 km or 30-month change interval for the 1986-1988 Eagle 258 under normal conditions is the longest drain interval across all entries in the specification set, more than double the 20000 km or 13-month interval listed for the 1981-1985 configurations.
