Friction drive CVT that evolved to traction drive CVT (T-CVT) was designed toward the end of 19th century, in a short period after automobiles were on the market. The T-CVT was made practicable in Japan in 1999 after approximately 100 years in advance of the world. Automobiles with the T-CVT have been accomplished as an integrated result of the progress of the following components: various machine elements, mechanism, design, processing technology, manufacturing technology, system control technology, material development, and traction oil development. The traction oil has an important function as one of the elements for the T-CVT unit. Its development and practical use have been the key to make T-CVT automobiles practicable. I would like to introduce out research and development of the traction oil showing the related characteristics.
