Additional Notes
- Both the 1.6 S and 1.9 S variants of the Opel Manta A share an identical automatic transmission fluid capacity of 2.5 liters, indicating no difference in transmission hardware between the two engine configurations for this service point.
- The 2.5-liter figure represents a service fill capacity, which typically refers to the amount of fluid required during a routine drain and refill rather than a full overhaul or dry fill of the transmission assembly.
- The capacity specification applies under normal use conditions for both the 1.6 S and 1.9 S, meaning the 2.5-liter figure is associated with standard operating circumstances rather than severe or heavy-duty service.
- Coverage spans the full 1970-1975 production range for both variants, with no variation in the 2.5-liter capacity recorded across any year within that period for either engine displacement.
