Additional Notes
- The Humber Sceptre Mark III carries an automatic transmission fluid capacity of 6.4 liters, which represents a service fill figure used during routine fluid maintenance.
- A 6.4-liter automatic transmission capacity places the Sceptre Mark III in a range typical of larger British saloon-era automatic gearboxes from the late 1960s and early 1970s, where fluid volume was generally higher than in modern compact units.
- The service interval for automatic transmission fluid on the Sceptre Mark III is set at 8,000 km or 6 months, whichever comes first, under normal use conditions.
- The dual-trigger interval of 8,000 km or 6 months under normal use reflects a time-based threshold alongside a distance-based one, meaning calendar aging of the fluid is treated as equally relevant as accumulated mileage.
- The specification applies exclusively to the Sceptre Mark III variant covering the 1967-1976 model years, with no differentiation noted across engine types or trim levels within that range.
