Manual transmission fluid capacity & service interval
Proton Persona manual transmission fluid specifications cover manual transmission fluid with capacities of 1.68 liter and 1.8 liter depending on configuration. The data includes two configurations. Capacity varies by configuration.

Additional Notes
- The Proton Persona 1.6 (2007-2016) manual transaxle carries two listed capacity figures: 1.8 liters and 1.68 liters, both recorded under normal use conditions.
- A capacity of 1.8 liters represents the larger of the two fill volumes on record for the manual transaxle, which may correspond to a full drain-and-refill or overhaul scenario where the entire fluid volume is displaced.
- The 1.68-liter figure is the smaller of the two capacities and may reflect a service fill, where residual fluid remains in the transaxle after a partial drain, reducing the volume required to return the unit to its specified level.
- Both capacity values apply exclusively to normal use conditions, meaning neither figure is associated with a severe-duty or extended-interval service designation in the available specifications.
- The 0.12-liter difference between the two listed capacities is a meaningful distinction in a transaxle of this size, as overfilling or underfilling a manual gearbox by even a small margin can affect lubrication film integrity and bearing performance.
