Additional Notes

  • The manual transaxle fluid capacity for the Subaru WRX VB with the 2.4T engine is 3.3 liters, a figure that reflects a service fill volume rather than a full overhaul or dry fill, as the transmission retains residual fluid during a standard drain procedure.
  • Under normal use conditions, the service interval for the manual transaxle is a fluid level check at 30,000 miles or 30 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions, the interval shifts to a full fluid change at 15,000 miles or 15 months, half the distance and time span associated with the normal-use check interval.
  • The 3.3-liter capacity figure applies consistently across both the normal and severe use rows, meaning the fluid volume involved in a severe-duty change is the same 3.3 liters regardless of the shortened interval.
  • The distinction between a check under normal conditions and a change under severe conditions reflects a meaningful difference in service scope, with the severe interval requiring complete fluid replacement rather than inspection alone.
