Maserati Quattroporte, AM 107

Additional Notes

• The Maserati Quattroporte AM 107 manual transmission specifications list two distinct fluid capacities: 1.1 liters and 1.8 liters. In manual transmission servicing, a lower figure typically corresponds to a partial drain-and-refill service fill, while a higher figure reflects the full overhaul or dry-fill capacity of the gearbox housing.
• Both capacity values, 1.1 liters and 1.8 liters, appear across all four engine and model year combinations covered in the specifications, meaning neither figure is exclusive to a particular displacement variant or production period.
• The 4200 and 4700 displacement variants share identical check and change intervals under normal use conditions: a fluid level check every 10,000 km and a full fluid change every 20,000 km.
• The 20,000 km change interval applies uniformly across the 1963-1967 and 1968-1970 production periods for both the AM 107 and AM 107/4700 designations, with no variation between the two periods in the specifications.
• The check interval of 10,000 km represents a mid-cycle inspection point, occurring at exactly half the 20,000 km drain interval, which is a common service structure intended to monitor fluid condition and level between full changes.
• All rows in the specifications carry a normal use condition designation, meaning the stated 10,000 km check and 20,000 km change intervals are associated exclusively with standard operating conditions rather than any severe or first-change scenario.
• The AM 107/4700 designation used for the 4700 displacement variant distinguishes it from the base AM 107 chassis code, yet the manual transmission fluid capacities and service intervals remain numerically identical across both designations throughout the 1963-1970 span.
