Proton Persona / Persona Compact

Automatic transmission fluid capacity & service interval

Proton Persona / Persona Compact automatic transmission fluid capacity is 6 liters. Service intervals include checking every 20000 km and changing every 40000 km or 24 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 Proton Persona / Persona Compact automatic transaxle holds 6 liters of fluid across both the 1.5 and 1.6 engine variants. A 6-liter figure for an automatic transaxle represents a full service fill, accounting for the fluid volume held within the torque converter, valve body, and transmission pan combined.
  • The 1.5 and 1.6 engine variants share identical automatic transaxle fluid capacity, check intervals, and change intervals across the 1993-2006 model years, indicating no differentiation in transmission specification between the two engine displacements.
  • Under normal use conditions, the automatic transaxle fluid check interval is set at 20,000 km for both the 1.5 and 1.6 variants. A check interval shorter than the change interval is standard practice, allowing fluid level and condition to be monitored between full drain-and-fill services.
  • The automatic transaxle fluid change interval under normal use conditions is 40,000 km or 24 months, whichever comes first. The dual-trigger format means time elapsed can mandate a fluid change even when the distance threshold has not been reached, which is relevant for vehicles driven infrequently.
