Additional Notes

  • The Triumph Dolomite 1300 manual transmission holds 0.85 liter, which represents the service fill capacity for a standard gearbox without overdrive.
  • The Dolomite 1500 shares the same 0.85 liter standard gearbox capacity as the 1300, but when fitted with an overdrive unit, the combined fluid capacity rises to 1.5 liters, reflecting the additional volume the overdrive housing requires.
  • The Dolomite 1850 manual transmission holds 1 liter in standard form, stepping up to 1.65 liters when an overdrive is fitted, making the overdrive addition responsible for an extra 0.65 liter of fluid volume.
  • The Dolomite Sprint carries the largest standard gearbox capacity across all four variants at 1.15 liters, and with overdrive, the total rises to 1.99 liters, the highest combined figure in the range.
  • Across the 1500, 1850, and Sprint, the overdrive unit consistently adds a meaningful volume of fluid on top of the base gearbox fill, with the added volume ranging from 0.65 liter on the 1850 to 0.84 liter on the Sprint.
  • All four variants share a uniform 10,000 km check interval under normal use conditions, applied consistently regardless of engine size or whether an overdrive unit is present.
  • The 1850 has the widest production window among the four, covering 1971-1980, while the 1300 and 1500 are specified from 1976-1980 and the Sprint from 1973-1980.
