Additional Notes
- The Lamborghini SIÁN Roadster carries a dry fill capacity of 3 liters for its semi-automatic transmission, a figure that represents the total volume required when filling a completely drained or rebuilt unit with no residual fluid remaining in the system.
- The service fill capacity is rated at 2.6 liters, which is the amount needed during a routine fluid change where some fluid remains in the torque converter or valve body after draining, accounting for the 0.4-liter difference from the dry fill figure.
- Under normal use conditions, the semi-automatic transmission fluid interval is set at a change every 30,000 km or 24 months, whichever comes first, pairing a distance-based threshold with a time-based limit to account for varying driving frequencies.
- A fluid level check interval of 15,000 km is specified under normal use, placing the inspection point at the midway mark between full change intervals.
- A first-change-only interval of 2,500 km is specified for the semi-automatic transmission, a break-in service designed to remove metal particles and manufacturing residues that accumulate during initial mechanical wear of new transmission components.
