Function
The plastic Electric Hydraulic Control Unit (EHU) is installed on the top of valve body. Speed sensor, start lock-out
switch and oil temperature sensors are integrated in EHU.
The 13-pin connector is connected to automatic transmission via PCB.
Three up/downshift solenoid valves are installed on the top of hydraulic control unit.
The solenoid valves are sealed with two O-rings against the valve body. The solenoid valves are pressed against
the valve body by the leaf springs.
Characteristics of up/downshift solenoid valve
The solenoid valve remains energized and therefore open
until the shift process is completed according to the engine
and transmission conditions. If a solenoid valve is energized,
it opens and transmits the shift valve pressure to the corre-
sponding command valve.
