Additional Notes
- The Vauxhall Cavalier Mk I automatic transmission service fill capacity is 2.5 liters across the 1.6, 1.9, and 2.0 engine variants. A service fill figure represents the fluid volume needed for a routine drain-and-refill procedure, which is typically less than the total system capacity measured during a full overhaul.
- All three Mk I engine variants share an identical check interval of 10,000 km or 6 months under normal use conditions, whichever comes first.
- The fluid change interval for all Mk I automatic transmission configurations is 40,000 km or 24 months under normal use conditions, pairing a distance threshold with a fixed time limit of two years.
- The 1.9-liter Mk I variant covers the 1975-1977 period, while the 2.0-liter Mk I spans 1977-1981, with both sharing the same 2.5-liter service fill capacity and identical check and change intervals despite the engine displacement difference.
- The 1.6-liter Mk I runs across the full 1975-1981 span of the generation and carries the same automatic transmission fluid specifications as the larger-displacement variants produced during overlapping years.
