Additional Notes
- The Opel Kadett C automatic transmission fluid capacity is 2.5 liters across both available engine configurations, the 1.2 S and the 1.6 S.
- A 2.5-liter figure for an automatic transmission service fill is consistent with a partial drain-and-fill procedure, which replaces only the fluid that drains from the pan rather than the full system volume that would be measured during an overhaul or complete flush.
- Both rows carry a normal use condition, meaning the 2.5-liter capacity is associated with standard operating conditions rather than a severe-duty or first-change interval.
- The 1.2 S configuration with automatic transmission covers the full 1974-1979 model range, while the 1.6 S with automatic transmission entered the lineup later, spanning 1977-1979.
