Additional Notes

  • The AMC Gremlin 121 carries an automatic transmission fluid capacity of 6.7 liters, which is noticeably lower than the 8 or 8.5 liter figures seen across the other engine variants, reflecting the smaller transmission unit paired with the four-cylinder engine.
  • The Gremlin 199 has the highest listed automatic transmission fluid capacity at 8.5 liters, and a check interval of 6,400 km under normal use conditions, which is shorter than the 9,600 km check interval specified for all other engine variants.
  • The 232, 258, and 304 V8 configurations all share an identical automatic transmission fluid capacity of 8 liters, with a check interval of 9,600 km under normal use conditions.
  • Under severe use conditions, the Gremlin 121 carries a fluid change interval of 38,500 km or 24 months, paired with a check interval of 9,600 km, applying to the 1977-1978 model years.
  • The 232 and 258 engines, spanning 1970-1978 and 1971-1978 respectively, share the same severe use change interval of 38,500 km or 24 months, alongside the same 8 liter capacity and 9,600 km check interval.
  • The Gremlin 304 V8, covering 1971-1976, also carries the 38,500 km or 24-month change interval under severe use conditions, with an 8 liter capacity and a 9,600 km check interval matching the inline-six configurations.
  • The 24-month time limit paired with the 38,500 km distance interval under severe use conditions across multiple variants means a fluid change is due at whichever threshold is reached first, a standard dual-trigger service approach.
  • Normal use conditions across all listed variants carry no fluid change interval, only a check interval, indicating that under normal use the specifications do not prescribe a scheduled drain and refill within the listed parameters.
