Torpedo All models

Manual transmission fluid capacity & service interval

Torpedo All models use manual transmission fluid with a capacity range of 18 to 50 liters. Service intervals include checking at 10 hours and changing at 1000 hours or 12 months. The data covers 6 configurations.

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

Additional Notes

  • The Torpedo RX 100 and RX 120 share an identical manual transaxle fluid capacity of 50 liters, the largest figure across all six models in this specification set.
  • The TX 48 and TX 55A carry the smallest transaxle capacity listed, at 18 liters each, reflecting the lighter-duty nature of those configurations relative to the larger TX variants.
  • The TX 75 holds 36 liters in its manual transaxle, while the TX 75A requires 41 liters despite sharing the same base designation, indicating a meaningful internal difference between the two variants.
  • A fluid check interval of 10 hours applies uniformly across all six models under normal use conditions, pointing to a maintenance schedule tied to operational hours rather than distance.
  • The RX 100 and RX 120 carry a change interval of 1000 hours with no calendar component, whereas the TX-series models pair the same 1000-hour threshold with a 12-month limit, whichever comes first.
  • The addition of a 12-month calendar interval on the TX 48, TX 55A, TX 75, and TX 75A means fluid age alone can trigger a change even when the hour threshold has not been reached under normal use conditions.
  • All six models cover the full 1986-1990 span without variation in service intervals across those years, meaning no model-year-specific adjustment to check or change schedules is reflected in the specifications.
