Noble M12 series

Manual transmission fluid capacity & service interval

The Noble M12 series uses manual transmission fluid with capacities ranging from 1.5 to 2.5 liters depending on the configuration. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
M12 GTO-3 (2001-2008)
  • Use: Normal
  • Capacity 1,5 liter
  • Code: 5/1
M12 GTO-3R (2001-2008)
  • Use: Normal
  • Capacity 2,5 liter
  • Code: 6/1
M400 (2001-2008)
  • Use: Normal
  • Capacity 2,5 liter
  • Code: 6/1

Additional Notes

  • The Noble M12 GTO-3 carries a manual transaxle fluid capacity of 1.5 liters, which is a relatively modest fill volume consistent with compact transaxle units found in lightweight sports cars.
  • The M12 GTO-3R and M400 variants both share a notably larger manual transaxle capacity of 2.5 liters, a full liter more than the standard GTO-3 specification.
  • All three configurations across the 2001-2008 model range list fluid capacity under normal use conditions, meaning the stated 1.5-liter and 2.5-liter figures apply to standard operating environments rather than severe or track-specific service.
  • The capacity difference between the GTO-3 and the GTO-3R suggests the two variants use mechanically distinct transaxle assemblies, as a 1.0-liter difference in fluid volume is too significant to attribute to minor design variation alone.
  • The M400 shares the same 2.5-liter transaxle fluid capacity as the GTO-3R across the full 2001-2008 span, indicating a common or closely related gearbox unit between the two higher-specification models.
  • All three M12 series configurations are noted as transaxle, manual arrangements, meaning the gearbox and final drive are housed in a single integrated unit, which is why a single fluid capacity figure covers the entire drivetrain assembly in each case.
