Additional Notes

  • The Nissan 240SX S14 manual transmission holds a service fill capacity of 2.4 liters across all listed model years from 1994-1998, meaning the figure reflects the amount of fluid needed during a routine drain-and-fill rather than a complete overhaul or dry fill.
  • Under normal use conditions, the service interval for the 1994-1996 240SX manual transmission is a fluid level check at 15,000 miles or 12 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions for the 1994-1996 model years, the interval shifts to an actual fluid change at 30,000 miles or 24 months, which is a notably different maintenance action compared to the normal-use check interval.
  • The 1996-1998 configuration carries the same 2.4-liter service fill capacity as the earlier 1994-1996 specification, indicating no change in transmission fluid volume across the S14 production span covered here.
  • For the 1996-1998 240SX under normal use, the manual transmission fluid check interval remains at 15,000 miles or 12 months, identical to the earlier model year range.
  • The severe-use change interval of 30,000 miles or 24 months also carries over unchanged into the 1996-1998 specification, maintaining consistency with the earlier production years.
  • The distinction between a fluid check under normal conditions and a fluid change under severe conditions is meaningful in practice, as a check only confirms fluid level and condition without necessarily replacing the fluid, while a change involves a full drain and refill to the 2.4-liter service fill capacity.
