Product Description
KATMOTO ATF DEXRON III is a high-performance automatic transmission fluid designed for older 4-speed and 5-speed automatic transmissions, torque converters, power steering systems and selected hydraulic applications requiring DEXRON III, DEXRON II or MERCON-type fluids. The balanced formulation provides smooth shifting, stable hydraulic response, oxidation resistance and reliable anti-wear protection for daily service conditions.
Key Performance Features
| Smooth shift feel for traditional automatic transmissions. | Stable friction performance for clutch and band engagement. |
| Anti-wear protection for gears, bearings and hydraulic components. | Good oxidation control for routine service and warm climates. |
| Low-temperature fluidity to support cold-start operation. | Foam, rust and corrosion control for stable hydraulic pressure. |
Applications & Performance Level
| Applications | Older 4AT/5AT automatic transmissions, torque converters, power steering systems and hydraulic systems where DEXRON III / DEXRON II / MERCON-type ATF is specified. |
| Suitable For | DEXRON III H/G/F-type, DEXRON II E/D-type, Ford MERCON-type, Allison C-4-type, Caterpillar TO-2-type, MAN 339 V1/Z1-type, MB 236.1/236.5/236.9-type, ZF TE-ML 03D/04D/11A/14A/17C-type. |
| Important Notice | Not recommended for CVT, DCT, DEXRON VI-only, low-viscosity ATF, or OEM-specific applications unless the vehicle manufacturer allows DEXRON III-type fluid. |
