Maserati Indy, AM 116

Additional Notes

• The Maserati Indy 4200 (AM116) carries a manual transmission fluid capacity of 1.1 liters, a fixed single value that reflects a service fill quantity for a sealed unit rather than a range accounting for residual fluid during a drain.
• Both the Indy 4700 (AM116/47) and the Indy 4900 (AM116/49) share a capacity range of 1.1 to 1.2 liters, which typically indicates a fill tolerance where the lower figure represents a minimum acceptable level and the upper figure represents a full service fill.
• The 4200 variant's fixed 1.1-liter capacity sits at the lower bound of the range seen in the 4700 and 4900 variants, reflecting a difference tied to the displacement and gearbox configuration rather than a shared unit across all three engine sizes.
• All three configurations share an identical check interval of 10,000 km under normal use conditions, meaning the fluid level is inspected at that mileage point without a full drain and refill being performed.
• The change interval across all three variants is set at 20,000 km under normal use conditions, placing the full fluid replacement at twice the frequency of the inspection interval.
• The Indy 4700 production began in 1970, one year after the 4200, while the Indy 4900 entered production in 1973, making the 4900 the shortest-lived of the three within the 1969-1974 span covered by these specifications.
• The uniform 10,000 km check and 20,000 km change intervals across all three variants, regardless of engine displacement, indicate that the service schedule was standardized at the platform level rather than varied by powertrain output.
