Additional Notes
- The Bentley Turbo R/S/RT automatic transmission carries a fluid capacity of 4.25 liters, a figure consistent with a service fill rather than a full overhaul, which would typically require a notably higher volume to account for fluid retained within the torque converter and valve body.
- The 4.25-liter service fill capacity applies uniformly across the R, S, and RT variants spanning 1986-1999, indicating no differentiation in transmission fluid volume between those sub-models despite their distinct trim and performance characteristics.
- The specified change interval is 25,000 km or 12 months, whichever comes first, and is designated for normal use conditions, meaning the interval is not adjusted for more demanding driving scenarios within the listed specifications.
- A 12-month maximum interval regardless of mileage reflects the time-based degradation of automatic transmission fluid, where oxidation and moisture absorption occur independently of how far the vehicle has been driven.
