Additional Notes

  • The Iso Grifo automatic transmission fluid capacity is 2 liters across the GL300, GL340, and GL350 variants, a figure consistent with a service fill rather than a full overhaul capacity.
  • The GL300, GL340, and GL350 share an identical fluid check interval of 10,000 km under normal use conditions.
  • A fluid change interval of 20,000 km applies to all three Grifo Lusso variants under normal use, meaning the change interval is exactly double the check interval.
  • The GL300, GL340, and GL350 show no variation in automatic transmission fluid capacity or service intervals despite carrying different model designations, suggesting a shared drivetrain specification across the Grifo Lusso range from 1963-1974.
