HYDRAULIC PRESSURE CONTROL SYSTEM
DESCRIPTION
Utilizing the hydraulic pressure generated at the oil pump, the hydraulic pressure control system switches
fluid passages leading to each shift control element of the power train mechanism according to running
conditions, regulates the line pressure as well as lubricates each section of the transmission.
The following table shows operating conditions of the hydraulic pressure applied to each shift control ele-
ment in each shift position.
