Purpose - The purpose of this paper is to discuss a method that can evaluate the friction durability of automatic transmission fluid.
Design/methodology/approach - A small clutch was used to test the friction durability. The method adopts a similar sequence to that of SAE No. 2. Three commercial oils were studied. One of them meets the specification of the GM's DEXRONIIE and the others meet the DEXRONIII.
Findings - The results showed that two commercial oils have different friction durability. Two further samples were blended in the lab and friction durability was researched by this method.
Originality/value - The results showed that the samples have a good durability. The research indicates that the method is quite capable of distinguishing between some samples. The results also indicate the difference between the DEXRON specifications at friction durability.
