Additional Notes

  • The AMC Gremlin 199 with a standard manual transmission holds 0.7 liter of fluid, while the same engine paired with a manual-plus-overdrive unit requires 1.3 liters, nearly double the capacity, reflecting the additional gearing hardware contained in the overdrive assembly.
  • The Gremlin 121 carries a manual transmission fluid capacity of 1.1 liters under normal use conditions, with a check interval of 9600 km.
  • The Gremlin 199 manual transmission specifies a check interval of 6400 km under normal use conditions, which is shorter than the 9600 km interval associated with the larger-displacement engine configurations in the same model line.
  • The Gremlin 232 and Gremlin 258 share an identical capacity range of 0.7 to 1.2 liters for their manual transmissions, both under normal use conditions with a 9600 km check interval. A range rather than a fixed value typically indicates that multiple transmission variants were fitted across the production years of each engine.
  • The Gremlin 304 V8 lists two separate manual transmission capacity figures: 1.4 liters and 1.2 liters, both with a 9600 km check interval under normal use conditions, indicating that two distinct transmission units were available with the V8 engine during the 1971-1976 period.
  • At 1.4 liters, the larger of the two Gremlin 304 V8 manual transmission capacities is the highest fixed single-value capacity recorded across all Gremlin manual transmission configurations in the specifications.
