AMC Hornet

Automatic transmission fluid capacity & service interval

AMC Hornet automatic transmission fluid capacity ranges from 8 to 9 liters. Service intervals include checks at 6400 km and 9600 km, and changes at 38500 km or 24 months. The data covers 11 configurations.

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

Additional Notes

  • The AMC Hornet 199 carries an automatic transmission fluid capacity of 8.5 liters, which is the largest figure among the six-cylinder configurations listed. A higher total fill volume generally reflects a larger transmission pan or torque converter capacity relative to the unit's displacement pairing.
  • The 199 engine configuration specifies a fluid check interval of 6,400 km under normal use, which is notably shorter than the 9,600 km check interval shared by all other engine variants in the lineup.
  • The 232, 258, and 304 V8 configurations all share an 8-liter automatic transmission fluid capacity, while the 360 V8 and SC360 configurations each carry a 9-liter capacity. The additional liter in the larger-displacement pairings is consistent with the greater fluid volume demands of transmissions matched to higher-output engines.
  • Under severe use conditions, the 232 (1970-1977), 258 (1971-1977), 304 V8 (1970-1977), 360 V8 (1972-1977), and SC360 (1971-1974) configurations all specify a fluid change interval of 38,500 km or 24 months, whichever comes first. Severe use classifications typically account for operating conditions such as frequent towing, stop-and-go traffic, or extreme temperatures that accelerate fluid degradation.
  • The normal use rows for the 232, 258, 304 V8, 360 V8, and SC360 configurations list only a check interval of 9,600 km, with no fluid change interval specified under that condition.
  • The Hornet SC360 shares the 9-liter transmission fluid capacity with the 360 V8, which aligns with the SC360 being a performance-oriented variant built around the same engine family. Both configurations apply the same 38,500 km or 24-month change interval under severe use.
  • The 258 engine configuration enters the specification range in 1971, while the 232 configuration spans the full 1970-1977 period, making the 232 the only six-cylinder engine with automatic transmission data covering the entire model range documented here.
