Additional Notes

  • Triumph 2000/2.5 PI/2500 manual transmission fluid capacities range from 1.14 liter to 1.6 liter for standard gearboxes, with additional volume required when overdrive units are fitted.
  • The 2.5 PI Mk 1 (1968-1969) lists a base capacity of 1.42 liter, rising to 2.46 liter with overdrive fitted, the largest combined figure among the listed configurations.
  • The 2000 Mk 1 (1963-1969) specifies a capacity of 1.14 liter, the lowest figure among the listed configurations.
  • Beginning with the Mk 2 generation, covering 2.5 PI, 2000, 2000TC, 2500S, and 2500TC variants, standard gearbox capacity settles at 1.6 liter, increasing to 2 liter when overdrive is fitted.
  • Overdrive-equipped configurations require roughly 0.4 to 1 liter more fluid than standard gearboxes, reflecting the added volume of the overdrive unit housing mounted to the rear of the transmission.
  • Fluid checks across every listed configuration occur at 10000 km intervals under normal use conditions.
  • The 2500TC Mk 2 appears with two overlapping production spans, 1974-1975 and 1974-1977, though fluid capacity and check interval remain identical between both entries.
  • Across the years 1963 through 1977, capacity figures pertain to service fill amounts for the gearbox rather than total system volume following a full overhaul.
