Rolls-Royce Ghost I, RR4

Additional Notes

• The Rolls-Royce Ghost I (RR4) automatic transmission carries a fluid capacity of 9.3 to 10 liters across all listed configurations, a range that reflects the difference between a partial service fill and a complete overhaul fill where the torque converter is also drained and refilled.
• The 0.7-liter spread between the lower and upper capacity figures is a practical consideration during service, as a fill stopping at 9.3 liters may indicate the torque converter retained residual fluid, while reaching 10 liters typically corresponds to a fully drained system.
• All four configurations share an identical service interval of 24 months or 30,000 km under normal use conditions, meaning whichever threshold arrives first triggers the recommended fluid check.
• The standard Ghost trim spans two separate row entries covering 2010-2018 and 2018-2020, yet both carry the same 9.3-10 liter capacity and the same 24-month/30,000 km check interval under normal use.
• The Ghost Black Badge, listed for 2017-2020, shares the same transmission fluid capacity range and service interval as the standard Ghost, indicating no mechanical differentiation in the automatic transmission system between the two variants at the specification level.
• The Ghost V-Specification, covering 2014-2017, also aligns with the 9.3-10 liter capacity and the 24-month/30,000 km check interval, placing all four listed configurations on a uniform service schedule regardless of trim designation.
• A 30,000 km interval on a vehicle in the Ghost class reflects a relatively conservative distance threshold, consistent with manufacturer practices for high-displacement luxury transmissions where fluid degradation is monitored on a time basis as much as a mileage basis.
• The dual-trigger interval structure, combining a calendar period of 24 months with a distance limit of 30,000 km, means low-mileage vehicles driven fewer than 30,000 km within two years still reach the check interval on the time condition alone.
