▶ 4-3 sequence valve
The 4-3 sequence valve is a two position
spring loaded valve. It switches during 3-4
and 4-3 gearshifts although it performs no
function during the 3-4 shift.
During the 4-3 shift the 4-3 sequence valve
delays the connection of the Clutch Apply
Feed (CAF) circuit to the B1R circuit until
the B1R circuit has been fully pressurized
by using the third gear circuit. This prevents
objectionable engine flare on completion of
the 4-3 gearshift.
▶ Solenoid supply pressure regulator
valve
The solenoid supply pressure regulator valve
supplies a constant pressure to all solenoids
(S1 to S7). Line pressure is used as the
feeding oil to this regulator and the output is
termed line 500.
▶ Line pressure control valve
Line pressure is controlled by S6, which
acts as the line pressure control valve.
When S6 pressure is applied to the end of
the Primary Regulator Valve (PRV), it is
opposed by spring force and causes LOW
line pressure for light throttle application and
cruising.
Heavy throttle application
normally open S6 to open (switch Off) thus
closing line 500 and opening S6 to exhaust.
Removal of S6 pressure from the PRV
results in HIGH line pressure.
