FIAT 9.55550-DA11

The FIAT 9.55550‑DA11 specification defines the requirements for transmission oils for Fiat (Stellantis) automatic gearboxes, in particular PowerShift models, 6‑speed and 7‑speed automatic transmissions installed in passenger cars, crossovers and light commercial vehicles. Oil that complies with this approval must have stable viscosity over a wide temperature range, provide precise friction control for smooth shifting, high resistance to oxidation and wear protection under high load. The specification provides compatibility with electronically controlled transmission management systems and does not require special SAPS or DPF requirements, as it is a transmission, not an engine oil. Using oil approved under FIAT 9.55550‑DA11 guarantees compliance with the manufacturer’s warranty conditions and extends the life and efficiency of the automatic transmission.
