Additional Notes
- The Proton GEN-2 / Persona automatic transaxle holds 7.7 liters of fluid across the 1.3, 1.6, and 1.6 ecologic variants introduced from 2004.
- A 7.7-liter figure for an automatic transaxle typically reflects a total system fill, accounting for fluid held within the torque converter, valve body, and transmission pan combined.
- The check interval for the automatic transaxle fluid is set at 9,000 miles or 12 months under normal use conditions, whichever comes first.
- The change interval extends to 27,000 miles or 36 months under normal use conditions, meaning the fluid is expected to remain serviceable across three check cycles before a full drain and refill is due.
- The 1.3 and 1.6 engine variants share identical automatic transaxle fluid capacity and service intervals, indicating no differentiation in transmission servicing requirements between the two displacements.
- The 1.6 ecologic variant also carries the same 7.7-liter capacity and the same 9,000-mile check and 27,000-mile change intervals as the standard 1.6, placing all three configurations on a uniform automatic transmission fluid service schedule.
