Additional Notes

  • The Ford FX 300, FX 375, and FX 450 each carry a manual transaxle fluid capacity of 1.5 liters, which is a typical fill volume for a compact transaxle unit rather than a full transmission overhaul quantity.
  • All three configurations share an identical check interval of every 50 hours, reflecting a routine inspection schedule intended to catch fluid level or condition issues well before the full change interval is reached.
  • The change interval across the FX 300, FX 375, and FX 450 is set at 400 hours or 12 months under normal use conditions, whichever comes first, meaning time elapsed can trigger a fluid change even when the hour threshold has not been met.
  • The hour-based interval structure on all three models points to equipment where engine runtime is tracked by an hour meter rather than odometer mileage, which is common in outdoor power or utility equipment applications.
  • No variation exists in manual transaxle fluid capacity or service intervals across the FX 300, FX 375, and FX 450 starting from 1994, despite the three models carrying different numeric designations that likely reflect differences in power output or configuration.
