175011~LlUpshift from
2nd to 3rd Gear\(1) When the shift control valve comes into
3rd gear position
and the
3rd pressure is established, the pressure is
directed to the No.7 port of the end clutch valve through
the No.7 line. In this instance, the
3rd pressure is blocked
ahead by the end clutch valve and the check ball.
(2) If a shift to the
3rd gear is initiated, the pressrue begins to
be directed from the
2-3/4-3 shift valve to the front clutch
and the release side chamber of kickdown servo cylinder.
The same pressure also is directed to the chamber at the
right end of the end clutch valve through the No. 12 line.
During the shift to the
3rd gear, the pressure in the No. 12
line is regulated by the pressure control valve to a level
lower than the line pressure so that the No. 12 line pressureis not high enough to force the end clutch valve toward the
left.(3) Once the front clutch has been engaged and the kickdown
brake released, the No. 12 line pressure is raised to a level .
equivalent to the line pressure.
This means that the pressures at both ends of the end
j
clutch valve (or No. 6 line pressure and No. 12 line pressure)[are at the same level. However, as the area of the
#3 land
to which pressure is applied is larger than that of the
# 1
land of the end clutch valve, the valve is pushed to left, thusopening the No.
18 port. This allows the 3rd pressure (line
pressure) already established in the No. 7 line to be directedto the end clutch through
the..No.7 port. The end clutch is
now engaged.
Downshift from
3rd to 2nd Gear
(1) Both front clutch pressure and kickdown servo release
pressure are released, and therefore, the pressure in
theend clutch valve right end chamber is also released.
--
(2) This results in a rightward movement of the end clutclvalve by the
2nd pressure working on its left end, closingthe
No.7 port and releasing the end clutch pressurethrough the No.8 port. Now the end clutch is released,

E,Upshift from
3rd to 4th Gear
(1) When the 4th pressure from the shift control valve is
directed to the rear clutch exhaust valve through the No.8
line, it pushes the elements “A” and
“B” of the rear clutch
exhaust valve to the right.
(2) The element “B” of the rear clutch exhaust valve that has
been moved towards the right closes the
No.5~ line port.
This prevents the line pressure coming from the N-D
control valve from being directed to the rear clutch.
(3) The line pressure supplied to the rear clutch is discharged
from the No. 15 line through the No.20 and No.20a lines.
This releases the rear clutch.
Downshift from 4th to
3rd Gear
(1) If the
4th pressure from the shift control valve is dis-
charged, the element “A” of the rear clutch exhaust valve
is pushed to the left under the line pressure established in
the
No.5~ line. This line pressure is directed to the rear
clutch via the No.20 line, No.
20a line, and then No. 15 line.
In one of the passages connecting the No.20 line with the
No. 20a line, there is a check ball and in the other there is anorifice. When one passage is closed by the check ball, the
fluid flows through the other passage with an orifice, which
slows down the fluid flow speed, permitting gradual
transaxle of pressure to the No.20a line to create condi-
tions ready for the rear clutch to operate.
(2) When the
2-3/4-3 shift valve operates and the hydraulic
pressure acts on the front clutch and the release side
chamber of kickdown servo cylinder, the pressure is
directed through the No. 12 line to the right end of the
element
“8” of the clutch exhaust valve.
Combined with the spring force, this pressure pushes the
element “B” of the valve to the left. This allows the high
line pressure in the
No.5~ line to be directly transmitted to
the rear clutch through the No. 15 line.

SEAT BELTSRZ3SBAS
On Federal and California vehicles automatic seat belts (Manualseat belts on vehicles for Canada) are installed on the front
seats and the
3-point seat belts with ELR on the rear seat, both
contributing to the enhanced safety and ease of use.
AUTOMATIC SEAT BELTS
GENERAL INFORMATION
The Automatic Seat Belts are designed to automatically fasten
themselves around the driver and front passenger as they get
into the vehicle and close the front door, thereby,
by a
combination of the lap belt, the knee protector, the corner pad
and the glove box pad (at the lower part of the instrument
panel), protecting them from second collisions during a
front-end crash or similar accident.
The lap belt for the driver’s seat is provided with the ELR
(ELR:Emergency Locking Retractor), and that for the front passen-
ger’s seat with the
ELR-ALR” to support the Child Restraint
System incorporated into the seat. (“ALR: Automatic Locking
Retractor) The buckle tilts toward front and inside helping the
belts be tight around the body.
The
tongue plate on the driver’s seat is provided with
energy-absorbing structure.
The automatic seat belts consist of a driving-device assembly,
shoulder belt, manual lap belt, knee protector, and other
components.
The driving-device assembly is composed of the slide anchor,
the release switch, the guide rail, the “fasten” switch, the
automatic seat belt motor relay, and the driving device.
There is an emergency-release button on the slide anchor; this
button can be used to release the shoulder belt in the event of
an emergency resulting from an accident, etc.
