Additional Notes
- The Maserati Merak / AM 122 manual transmission fluid specifications cover a transaxle configuration, meaning the transmission and rear axle differential share a combined housing rather than being separate units.
- Both the Merak SS USA (AM 122/A80) and the Merak SS (AM 122/A) carry an identical transaxle fluid capacity of 2.25 liters across the 1976-1983 model years.
- A 2.25-liter capacity is relatively modest and consistent with a compact transaxle unit, reflecting a service fill volume rather than a full overhaul or dry-fill figure.
- The fluid listed for both configurations carries an "alternative (acceptable)" use designation, indicating a secondary fluid type that falls within approved limits rather than the primary recommended specification.
- A check interval of 10,000 km applies to both the AM 122/A80 and AM 122/A transaxles, meaning the fluid level is inspected at that mileage point without necessarily being replaced.
- The change interval is set at 20,000 km for both variants, placing the full fluid replacement at twice the frequency of the check interval.
- The AM 122/A80 designation identifies the North American market version of the Merak SS, yet the transaxle fluid capacity and service intervals are identical to the standard AM 122/A, with no regional variation in those specifications.
