Additional Notes

  • The Ford Cortina Mk I (EU) manual transmission holds 1 liter of fluid across all three available variants: the 1200, the 1500, and the Lotus.
  • A 1-liter transmission capacity is characteristic of compact gearboxes from this era, reflecting the relatively small displacement engines and lightweight construction of the Cortina Mk I platform.
  • The check interval for manual transmission fluid is set at 8,000 km or 5,000 miles across all three variants, applied under normal use conditions.
  • The specifications list a fluid check interval rather than a full drain-and-refill service interval, meaning the 8,000 km / 5,000 miles figure represents how often the fluid level is to be inspected rather than replaced outright.
  • The Cortina Lotus, produced from 1963-1966, shares the same 1-liter transmission capacity and 8,000 km check interval as the base 1200 and 1500 variants, despite housing a more performance-oriented twin-cam engine developed with Lotus.
  • The uniformity of the 1-liter capacity and 8,000 km check interval across the 1200 and 1500 engine variants, covering the full 1962-1966 production span, indicates a common gearbox unit was used regardless of engine displacement within the standard Cortina Mk I range.
