A study on bench test for automatic transmission fluid friction durability
Abstract
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.
