In addition, in the existing vehicle type equipped with a hydraulic transmission (AT), transmission oil cooling is required, and transmission cooling is divided into an indirect cooling method of water cooling oil and direct cooling of air cooling oil, and if a supercharged engine is used as the engine, an intercooler for cooling the supercharged air is also required to be added.
