Proton GEN-2 / Persona

Manual transmission fluid capacity & service interval

Proton GEN-2 / Persona manual transmission fluid capacity is 2,1 liters. Service intervals include checking every 9000 miles or 12 months and changing every 27000 miles or 36 months. The data covers 3 configurations.

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

Additional Notes

  • The Proton GEN-2 / Persona manual transaxle holds 2.1 liters of fluid across the 1.3, 1.6, and 1.6 ecologic variants introduced from 2004. A 2.1-liter fill is a typical service-level capacity for a compact front-wheel-drive transaxle, meaning the figure reflects a drain-and-refill quantity rather than a full overhaul or disassembly fill.
  • All three engine variants share an identical fluid check interval of 9,000 miles or 12 months under normal use conditions, whichever comes first. The dual-trigger structure means a calendar limit applies even when annual mileage stays below the distance threshold.
  • The fluid change interval across the 1.3, 1.6, and 1.6 ecologic configurations is set at 27,000 miles or 36 months under normal use. At exactly three times the check interval distance, the change schedule aligns with every third fluid inspection cycle.
  • The 36-month change interval means a full fluid replacement is due roughly every three years when mileage accumulation is low. In practice, the time-based trigger would govern for drivers covering fewer than 9,000 miles annually.
  • The 1.3 and 1.6 variants share the same 2.1-liter capacity despite the difference in engine displacement. Manual transaxle volume is generally determined by the gearbox casing geometry rather than engine size, which accounts for the uniform figure across both configurations.
  • The 1.6 ecologic variant carries the same transaxle fluid capacity and service intervals as the standard 1.6. No specification difference exists between the two 1.6 configurations in the manual transmission fluid data for the 2004 introduction year.
