Additional Notes

  • The Nissan 240SX S14 automatic transmission carries a service fill capacity of 8.3 liters across all listed model years from 1994-1998. A service fill figure reflects the amount of fluid needed during a routine drain-and-fill procedure, not the total system volume that would apply during a full overhaul or torque converter replacement.
  • Under normal use conditions for the 1994-1996 240SX, the specification calls for a fluid check at 15,000 miles or 12 months, whichever comes first. A check interval rather than a change interval indicates the fluid level and condition are being monitored rather than replaced on that schedule.
  • Under severe use conditions for the 1994-1996 240SX, the specification shifts from a check to an actual fluid change at 30,000 miles or 24 months. Severe use typically involves conditions such as frequent towing, stop-and-go driving, or extreme temperatures, which accelerate fluid degradation and justify a full replacement rather than inspection alone.
  • The 1996-1998 240SX shares the identical 8.3-liter service fill capacity with the 1994-1996 configuration, and the normal-use interval of a fluid check at 15,000 miles or 12 months also remains unchanged between the two year ranges.
  • The severe-use change interval of 30,000 miles or 24 months carries over without modification from the 1994-1996 range into the 1996-1998 range, meaning the automatic transmission service schedule remained consistent across the full 1994-1998 production span covered in these specifications.
