Triumph Spitfire

Additional Notes

• The Triumph Spitfire 4 (1962-1965) and Spitfire MK2 (1965-1967) share a fixed manual transmission fluid capacity of 0.9 liter, indicating a single defined fill volume with no range variation across those variants.
• Beginning with the Spitfire MK3 (1967-1970), the manual transmission fluid capacity shifts to a range of 0.9-1.4 liters, a pattern that continues through the MK IV (1970-1974) and the Spitfire 1500 (1974-1980). A capacity range rather than a fixed value typically reflects differences between a drain-and-refill service fill and a full overhaul or dry fill.
• The 0.5-liter spread between the low and high ends of the 0.9-1.4 liter range, present in three of the five variants, represents a meaningful difference in fluid volume and is relevant when determining whether a transmission is being refilled after a partial drain or rebuilt from a dry state.
• All five Spitfire variants share an identical fluid check interval of 9,600 km (6,000 miles) under normal use conditions, applied consistently across the full 1962-1980 model span covered in the specifications.
• The fluid change interval across all listed variants is 19,200 km (12,000 miles) under normal use conditions, exactly double the check interval, meaning a fluid level inspection falls at the midpoint of every change cycle.
• All specifications are designated for normal use conditions, meaning the check and change intervals of 9,600 km and 19,200 km respectively are not adjusted for any alternative operating condition within the data provided.
• The transition from a fixed 0.9-liter capacity in the Spitfire 4 and MK2 to the wider 0.9-1.4 liter range in the MK3 coincides with the 1967 model year, while the service intervals remain unchanged across that same transition point.
