Additional Notes

  • The Triumph GT6 rear differential holds 0.6 liters across all three production variants, covering the MK1, MK2/GT6+, and MK3 generations from 1966-1973.
  • A 0.6-liter capacity is a relatively modest fill volume, consistent with the compact rear axle unit found in small British sports cars of the era.
  • The specified interval for the rear differential is a fluid level check at 20,000 km or 12,000 miles, applied under normal use conditions for all three variants.
  • The GT6 MK1 (1966-1968), MK2/GT6+ (1968-1970), and MK3 (1970-1973) share identical rear differential capacity and check interval figures, indicating no revision to the differential specification across the model's production run.
