Specific frictional properties are essential to provide correct and pleasurable shifting in a manual transmission. Synchroniser rings are being manufactured from an increasingly wider range of materials, and so it is important to understand synchroniser-additive interactions in order to develop tailored lubricants that provide the desired frictional performance. This paper describes a study of the interaction of various friction modifier additives with a range of synchroniser materials in order to better understand the potential to develop lubricants that provide optimal frictional performance across a wide range of manual transmission-synchroniser systems. This presentation will outline the results of testing fluids with a range of synchroniser materials and will be followed by a future paper that will describe details of the fluids and analysis of their interactions with the different synchroniser surfaces.
