Automatic Transmission FLuids

Click Bottles Below for More Detail

Automatic transmission fluids (ATF) are used in the transmissions of passenger cars, trucks, construction equipment, and other mobile equipment. In addition, ATF finds use in such non-transmission applications, as hydraulic systems, compressors, power steering, and others. 

 

There are numerous types of ATF, including, Dexron II, Dexron III, Type F, Mercon, Mercon V, Chrysler 7176 and several varieties of Chrysler ATF-Plus.

Automatic transmissions are very sensitive to the types of ATFs used. Use of the wrong fluid, can cause transmission problems. Always read THE OWNER'S MANUAL! Advanced Auto Parts Dex III/M Marathon Multi-Purpose ATF Brad Penn IIIH® SuperS Multi-Purpose D/M ATF Liberty Gold Plus ATF

 a- Standards, shown in black are established by Original Equipment Manufacturers for Dexron III/Mercon. Ranges, shown in teal, represent the high and low data for the major brands of tested in February 2012.

b- Dexron® III, 170C max, Mercon®, 177 C max.

c-Test Method used for metal analysis is ASTM ASTM D5185.

d- ASTM D5185-09 Reproducibility by Element.

e-PQIA's test results for this sample slightly exceeds the Dexron III and Mercon specification for Brookfield Viscosity @ -40C of 20,000 cP maximum.  Reproducibility for this test is +- 1,850 cP.
