Rymax Atexio II Automatic Transmission fluid ATF (20LT)

Atexio II is a mineral based automatic transmission fluid, and ranks amongst the most complex lubricants on the market at present. Blended from as many as 15 different components, ATFs represent a careful balance of properties needed to meet the unique requirements of automatic transmissions. 

These fluids perform five basic functions:

• Transmit hydronamic energy in the torque converter.
• Transmit hydrostatic energy in hydraulic logic control circuits and servomechanisms.
• Lubricate shaft bearings, thrust bearings and gears.
• Transmit sliding friction energy in bands and clutches.
• Act as a heat transfer medium controlling automatic transmission operating temperatures.

ATF specifications are in a state of flux and now there are several types of fluid specified for North American transmissions. The ATF used for older vehicles mostly is our DEXRON® II, recommended for transmission top-up or refill, by most automobile manufacturers.

Our Atexio II demonstrates outstanding oxidative and thermal stability, giving extremely long service life over the most severe operating conditions. The fluids operating range is between –40 °C and + 160 °C. It has been tested extensively and meets General Motors specification 6297M.

Atexio II has excellent cold starting performance, superior materials compatibility and a great resistance to oxidation. It may be used in power steering units specifying a DEXRON® II type fluid.
