Additional Notes
- The Rover P5 3-Litre MK I and MK II, covering 1959-1965, share an identical automatic transmission fluid capacity of 8.5 liters, along with the same check interval of 5,000 km and change interval of 20,000 km under normal use conditions.
- The 3-Litre MK III (1965-1967) and the 3.5-Litre (1967-1973) both carry a reduced capacity of 8 liters, which is 0.5 liters less than the earlier MK I and MK II specifications.
- A transmission fluid capacity in the range of 8 to 8.5 liters is consistent with a full system fill, meaning the figure accounts for the fluid held within the torque converter, valve body, and transmission case together rather than a partial drain-and-fill service quantity.
- The MK I and MK II specifications include a defined change interval of 20,000 km under normal use, while the MK III and 3.5-Litre rows carry no change interval, only a check interval of 8,000 km.
- The check interval shifts from 5,000 km in the 1959-1965 MK I and MK II variants to 8,000 km in the MK III and 3.5-Litre variants, representing a 60 percent increase in the distance between fluid level inspections across the model's production span.
- All four configurations are specified under normal use conditions, meaning the intervals listed reflect standard operating environments rather than severe-duty cycles such as towing, extreme temperatures, or predominantly short-trip driving.
