Peugeot 408, P54

Additional Notes

• The Peugeot 408 P54 automatic transaxle carries a dry fill capacity of 6 liters across the 1.2 PureTech 130 (HNS), HYBRID 180 (DGX), and HYBRID 225 (DGY) configurations. A dry fill figure represents the total fluid volume required when filling a completely drained or newly assembled unit, including all internal passages and the torque converter.
• The service fill capacity is listed as a range of 2.5 to 3.5 liters for all three configurations. A service fill range rather than a fixed value reflects the variable amount of fluid that drains during a routine fluid exchange, which depends on factors such as drain time, fluid temperature, and whether the pan is removed.
• The gap between the 6-liter dry fill and the 2.5-3.5 liter service fill range indicates that a standard fluid exchange replaces roughly half or less of the total fluid volume in the transaxle. The remainder stays retained in the torque converter and other internal circuits that do not fully drain during a conventional service.
• All three configurations share identical dry and service fill capacities despite differing powertrains. The 1.2 PureTech 130 is a petrol-only engine, while the HYBRID 180 and HYBRID 225 variants integrate electric motors alongside internal combustion engines, yet the automatic transaxle fluid specifications remain uniform across all three.
• All rows are designated under normal use conditions, meaning the listed service fill range of 2.5 to 3.5 liters applies to standard operating environments rather than elevated-stress or severe-duty cycles.
