Additional Notes

  • Rear differential fluid capacity across the Triumph 2000/2.5 PI/2500 range spans 1 liter to 1.15 liters, depending on Mark generation and engine configuration.
  • Mk1 variants, including the 2.5 PI Mk1 (1968-1969) and 2000 Mk1 (1963-1969), specify a 1 liter fill for the rear differential.
  • Mk2 variants, covering the 2.5 PI Mk2, 2000 Mk2, 2000TC Mk2, 2500S Mk2, and 2500TC Mk2, specify a 1.15 liter fill, a 0.15 liter increase over Mk1 figures.
  • All listed configurations apply a 10000 km inspection interval for rear differential fluid under normal use condition.
  • The 2500TC Mk2 entry lists two overlapping production spans, 1974-1975 and 1974-1977, both carrying the same 1.15 liter capacity and 10000 km inspection interval.
  • The 2000 Mk1 (1963-1969) production span covers six years, contrasting with the shorter 1968-1969 span of the 2.5 PI Mk1, though both share identical 1 liter capacity and inspection interval figures.
  • Fluid capacity increase from Mk1 to Mk2 applies uniformly across four-cylinder (2000, 2000TC) and six-cylinder (2500S, 2500TC) engine variants within the Mk2 lineup, each listed at 1.15 liters.
