Overview
DEX III is a semi-synthetic automatic transmission fluid of the DEX III type. The product name identifies the transmission-fluid type it is formulated for; it is not a statement of approval by any vehicle or transmission manufacturer.
Published typical values are 33 cSt at 40 °C and 7.5 cSt at 100 °C, a viscosity index of 210 and a pour point of -36 °C. Flash point, appearance and copper corrosion are also listed in the specification table.
Application
Use where the vehicle or transmission manual names this fluid type. Confirm the exact fluid specification before filling.
Feature
Pour point of -36 °C (ASTM D97) with a viscosity index of 210 (ASTM D2270).
Feature
33 cSt at 40 °C and 7.5 cSt at 100 °C (ASTM D445).
Feature
Copper-strip corrosion at 100 °C (ASTM D130) is part of the published test set.
No. The name describes the fluid type. Transmission manufacturers issue their own approvals; check the manual and ask us for documentation before use in a vehicle under warranty.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
