Step type automatic transmissions (AT’s) have undergone significant development with increasing gear ratios and longer service intervals, high performance friction materials and complex hydraulic shift systems.
Grease is formed by emulsifying liquid lubricant in a thickening agent like soap. The liquid lubricant in the grease generally is mineral oil or synthetic oil.
Used oil analysis is typically a scheduled activity for analyzing oil health, oil contamination and machine wear. While the main purpose of an oil analysis program is to verify the lubricant in use is fit for further service, the analysis result is also used to diagnose whether the lubricated machine is operating normally.
