JAC S2

Manual transmission fluid capacity & service interval

JAC S2 manual transmission fluid capacity is 2 liters. Service intervals include checks at 10000 km or 6 months, and changes at 3000 km or 3 months and 20000 km or 12 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The JAC S2 1.5 manual transaxle holds a fluid capacity of 2 liters, a figure consistent with compact front-wheel-drive transaxle designs where the gearbox and differential share a common housing and a single fluid fill.
  • Under normal use conditions, the manual transaxle fluid check interval is set at 10,000 km or 6 months, whichever comes first, while the change interval extends to 20,000 km or 12 months.
  • A separate first-change-only interval is specified at 3,000 km or 3 months, applying the same 2-liter capacity. A first-change interval at such a short distance is associated with flushing out metal particles and manufacturing residues that accumulate during the initial break-in period of new gear and bearing surfaces.
  • The gap between the first-change interval of 3,000 km and the subsequent normal change interval of 20,000 km reflects a two-phase service approach, where early fluid replacement addresses break-in contamination before the standard long-term schedule takes effect.
