Abstract
This invention relates to a fluid pressure supplying method for fluidically actuating a frictional engaging apparatus in a vehicle transmission, including the steps of supplying high pressure to actuate the frictional engaging apparatus, reducing the high pressure to a lower pressure when the frictional engaging apparatus is initially engaged, and increasing the fluid pressure to line pressure in the frictional engaging apparatus after the frictional engaging apparatus is fully engaged, thereby smoothly engaging the frictional engaging apparatus without giving a shock to the apparatus and reducing the engaging time of the frictional engaging apparatus.
