Product Description
KATMOTO HYBRID DHT FLUID is a dedicated hybrid transmission fluid developed for selected DHT and hybrid e-ATF systems used in modern plug-in hybrid and hybrid vehicles. The balanced low-viscosity formulation supports efficient gear transmission, electric motor compatibility, copper-component protection, clutch control, thermal stability and smooth transition between engine and electric drive modes.
Key Performance Features
| Developed for selected dedicated hybrid transmission systems. | Low-viscosity formulation supports transmission efficiency. |
| Protects gears, bearings, clutches and electric motor components. | Copper-compatible additive system for electrified drive units. |
| Smooth engine/electric mode transition and clutch control. | Oxidation, foam and corrosion control under high thermal load. |
Applications & Performance Level
| Applications | Selected DHT and hybrid e-ATF systems in BYD DM-i, Geely Leishen, Chery DHT, GWM Hi4 and similar hybrid transmission architectures where compatible DHT fluid is specified. |
| Suitable For | DHT-type hybrid transmission applications requiring low-viscosity e-ATF/DHT fluid with electric motor and gear protection performance. |
| Important Notice | DHT fluid requirements vary by OEM and model. Do not use as a universal ATF, CVTF, DCTF or e-CVT fluid unless compatibility is confirmed by the service manual. |
