Why Rymax Atexio III ATF
Dexron III Compliance
Meets Dexron III required by GM and a wide range of manufacturers for automatic transmissions built before the Dexron VI era — backwards compatible with Dexron II applications.
Excellent Low-Temperature Fluidity
Pour point of -42°C ensures rapid ATF circulation at cold start — critical for smooth gear engagement and transmission protection in cold conditions.
Friction Stability
Balanced friction modifier package maintains consistent frictional characteristics — ensuring smooth gear shifts throughout the service interval.
Oxidation Resistance
Additives resist oxidative breakdown under high ATF operating temperatures — maintaining fluid integrity and shift quality.
Power Steering Compatibility
Suitable for power steering systems where an ATF is specified — providing consistent flow and pressure characteristics.
Anti-Wear & Anti-Foam
Comprehensive anti-wear and anti-foam additive package protects pump, valve body and clutch pack components.
Recommended Applications
Automatic Transmissions
Older generation automatic gearboxes where Dexron II or Dexron III ATF is specified.
Power Steering Systems
Hydraulic power steering systems in vehicles where an ATF is the specified fluid.
Classic & Older Vehicles
Pre-2005 automatic transmission vehicles where Dexron III is the correct specification.
Light Commercial Vehicles
Automatic transmissions in bakkies, vans and light trucks where Dexron III is specified.
Hydraulic Systems
Selected hydraulic systems requiring good low-temperature fluidity where ATF-type fluid is appropriate.
Workshop Use
General workshop ATF for Dexron II/III automatic transmission service and top-up.
