Manitou Forklift trucks, S-TC

Automatic transmission fluid capacity & service interval

Manitou Forklift trucks, S-TC use automatic transmission fluid with a capacity of 18 liters. Service intervals include checking every 150 hours and changing every 600 hours. The data covers 6 configurations.

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

Additional Notes

  • All six S-TC variants listed here pair the Ford 192 ci engine with a powershift transmission, and every one of them carries an automatic transmission fluid capacity of 18 liters. In forklift applications, an 18-liter fill is consistent with a full powershift transmission sump rather than a partial service top-up, indicating the figure represents total system capacity.
  • The Manitou S-TC models covered — S402TC-D, S404TC-D, S502TC-D, S504TC-D, S602TC-D, and S604TC-D — all share identical service intervals of a fluid level check at 150 hours and a full fluid change at 600 hours under normal use conditions.
  • The 150-hour check interval is notably shorter than the 600-hour change interval, reflecting the standard practice of monitoring fluid level and condition between full drain-and-fill services on powershift transmissions, where fluid degradation or minor leaks can affect shift quality before a scheduled change is due.
  • A 600-hour change interval on a powershift transmission is a moderate service cycle for industrial forklift equipment, where operating hours accumulate faster than in on-road vehicles. At typical warehouse shift patterns, 600 hours can represent several months of continuous operation.
  • The numeric designations in the model names — 402, 404, 502, 504, 602, 604 — suggest differences in load capacity or configuration across the S-TC range, yet the transmission fluid capacity and service intervals remain uniform across all six variants at 18 liters, 150-hour checks, and 600-hour changes.
  • All six specifications are rated for normal use conditions. In forklift service classifications, normal use typically refers to standard warehouse or light industrial operation, as opposed to severe-duty cycles involving extreme temperatures, heavy continuous loads, or highly contaminated environments.
