DS DS 3 Crossback, U

Additional Notes

• The DS 3 Crossback U automatic transmission fluid specifications cover three engine variants across the 2018-2022 model years: the 1.2 PureTech 130 (HNS), the 1.2 PureTech 155 (HNN), and the 1.5 BlueHDi 130 (YHZ).
• All three variants share an identical dry fill capacity of 6 liters, which represents the total fluid volume required when filling a completely drained or rebuilt transaxle unit from empty.
• The service fill capacity is listed as a range of 2.5-3.5 liters across all three variants, reflecting the variable amount of fluid retained in the torque converter and passages during a standard drain-and-fill service procedure.
• The gap between the 6-liter dry fill and the 2.5-3.5 liter service fill range indicates that roughly half or more of the total fluid volume remains in the transaxle during a routine service, which is a common characteristic of automatic transmission designs where full drainage without disassembly is not achievable.
• Each of the three engine variants is noted as a transaxle configuration, meaning the automatic transmission and final drive are housed in a single integrated unit, which is typical for front-wheel-drive platforms.
• The service fill range rather than a fixed value accounts for natural variation in how much residual fluid remains after draining, meaning the actual refill quantity falls somewhere between 2.5 and 3.5 liters depending on drain conditions and elapsed drain time.
• All specifications are designated for normal use conditions, and the capacity figures for both dry fill and service fill apply uniformly across the 1.2 PureTech 130, 1.2 PureTech 155, and 1.5 BlueHDi 130 engine codes without differentiation by powertrain type.
