Rolls-Royce Phantom Coupé, RR3

Additional Notes

• The Rolls-Royce Phantom Coupé RR3 carries two automatic transmission fluid capacity figures under normal use conditions: 9 liters and 8.5 liters.
• A 9-liter fill is the larger of the two values recorded, which typically corresponds to a dry fill or overhaul scenario where the torque converter and all internal passages are fully evacuated before refilling.
• The 8.5-liter figure represents the more conservative capacity, consistent with a service fill where residual fluid remains in the torque converter or valve body during a routine drain and refill procedure.
• The 0.5-liter difference between the two capacity values is a meaningful distinction in practice, as overfilling an automatic transmission can cause aeration of the fluid and pressure irregularities within the hydraulic circuit.
• Under normal use conditions, the specified check interval for the automatic transmission fluid is 24 months or 30,000 km, whichever comes first, as recorded alongside the 9-liter capacity figure.
• A time-based interval of 24 months runs parallel to the 30,000 km distance interval, meaning low-mileage operation does not exempt the transmission fluid from periodic inspection once two years have elapsed.
• The normal use condition tied to both capacity entries reflects standard operating environments, as opposed to severe or extended-duty cycles that would typically carry shorter service intervals.
• Both capacity entries apply uniformly across the 2008-2017 model years of the Phantom Coupé RR3, with no variation in fluid volume specifications recorded across that span.
