Manitowoc Mobile cranes
Manual transmission fluid capacity & service interval
Manitowoc mobile cranes use manual transmission fluid with a capacity range of 15,5 to 16,6 liters. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Manitowoc Mobile Cranes GMK3060 paired with the Cummins QSL9-C engine carries a manual transmission fluid capacity of 16.6 liters, which is a notably higher fill volume than the two Mercedes-Benz OM470LA-powered models in the same lineup.
- Both the GMK4080-2 and GMK4090 equipped with the Mercedes-Benz OM470LA engine share an identical manual transmission fluid capacity of 15.5 liters under normal use conditions.
- The 1.1-liter difference between the Cummins QSL9-C-powered GMK3060 at 16.6 liters and the OM470LA-powered models at 15.5 liters reflects a variation tied to the transmission unit matched to each engine configuration rather than crane size alone.
- All three configurations list normal use conditions for the manual transmission fluid capacity, meaning the 16.6-liter and 15.5-liter figures apply to standard operating environments rather than severe-duty cycles.
- A manual transmission capacity in the 15- to 17-liter range is consistent with heavy-duty commercial vehicle gearboxes, where larger sump volumes support thermal management across extended load cycles typical of crane carrier applications.
- The GMK4080-2 and GMK4090 share the same engine and the same 15.5-liter transmission fluid capacity, indicating both models use the same gearbox assembly despite being distinct crane configurations starting from 2017.
