The automatic transmission is a combination of a 3-element torque converter and triple-shalt electronically controlled
automatic transmission which provides 4 speeds forward and 1 speed reverse. The entire unit is positioned in line with
the engrne.
Torque Converter, Gears, and Clutches
The torque converter consists of a pump, turbine, and stator, assembled in sigle unit. The torque converter is connected to
the engine crankshaft so they turn torether as a unit as the engine turns. Around the outside of the torque convener is a
ring gear which meshes with the starter pinion when the engine is being started. The entire torque converter assembly
serves as a flywheel while transmitting power to the transmission mainshaft.
The transmission has three parallel shafts; the mainshaft. the countershaft, and the sub shaft. The mainshaft is in-line with
the engine crankshaft.
The mainshaft includes the 1st, and 2ndl4th clutches,and gear for 3rd, 2nd, 4th, reverse, and 1st. (3rd gear is integral with
the mainshaft, while reverse gear is integral with the 4th gear.)
The countershaft includes the 3rd clutch and gears for 3rd,2nd, 4th, reverse, 1st, and parking. Reverse and 4th gears can
be loched to the countershaft at its center,providing 4th gear or reverse, depending on which way the selector is moved.
The sub-shaft includes the 1st-hold clutch and gears fo 1st and 4th.
The gears on the mainshaft are in constant mesh with those on the countersahft and sub-shaft.When certain combinations
of gears in the transmission are engaged by clutches. power in transmitted from the mainshaft to the countershaft via the
sub-shaft to orovude oil, lo'1. E, E. and E.
Electronic Control
The electronic control svstem consists of the Transmission Control Module (TCM), sensors, and four solenoid valves.
Shilting and lock-up are electronically controlled for comfortable driving under all conditions.
The TCM is located below the dashboard, behind the lelt side kick panel on the driver's side.
Hydraulic Control
The valve bodies include the main valve body, the secondary valve body, the regulator valve body, the serbvo body, and
the lock-up valve body, through the respective separator plates, They are bolted to the torque converter housing,
The main valve body contains the manual valve, the 1-2 shift valve, the 2-3 shitt valve, the Clutch Pressure Control
lCPC) valve, the 4th exhaust valve, the reliel valve, and the ATF pump gears.
The secondary valve body contains the 4-3 kick-down valve, the 3-2 kick-down valve, the 2-3 orifice control valve, the
3-4 shift valve, the orilice control valve, the modulator valve, and the servo control valve.
The regulator valve body contains the pressure regulator valve, the lock-up control valve, the torque converter check
valve, and the cooler check valve.
The servo body contains the servo valve, which is integrated with shift fork shaft, the throttle valve B, and the accumula-
tors.
The lock-up valve body contains the lock-up shift valve and the lock-up timing B valve, and is bolted to the regulator valve
ooqy.
Fluid from the regulator passes through the manual valve to the various control valves.
Shift Control Mechanism
Input to the TCM from various sensors located throughout the car determines which shift control solenoid valve should
be activated. Activating a shitt control solenoid valve changes modulator pressure, causing a shift valve to move. This
pressurizes a line to one ol the clutches, engaging that clutch and its corresponding gear.
Lock-uD Mechanism
In @ position, in 2nd, 3rd and 4th, and @ position in 3rd, pressurized fluid can be drained lrom the back oI the tor-
que converter through a fluid passage, causing the lock-up piston to be held against the torque converter cover. As this
takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together with hydraulic control, the TCM
optimizes the timing of the lock-up mechanism.
The lock-up valves controlthe range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B.
When lock-up control solenoid valves A and B activate, modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.

- How the Circuit Works
The security system control unit has a 3 position
switch: Manual. Auto. and Auto Lock. Here's what
happens when you arm the system, regardless ol
the switch position:
o The parking lights will flash once.
. The security indicator will flash once per second
after the system is armed.
With the switch in the Manual position, the security
system can only be armed by using the remote
control transmitter, After you remove the key from
the ignition and close all doors, the hood (if
equipped with the optional hood switch), the hatch
or trunk. Dress the lock button on the transmitter
and the system will arm (if the system is in the beep
sound mode, the horn will sound once). The doors
will automatically lock when the system is armed.
With the switch in the Auto position, the security
system will arm itself within about 20 seconds after
you turn the engine off, remove the key from the
ignition, and close the halch or trunk, the hood (if
equipped with the optional hood switch), or last
door. lf a door is opened during the 2o-second exit
delay time, the timer will reset itself . The remote
control transmitler can still be used to arm the
system with the switch in Auto position (see manual
for details).
With the switch in Auto Lock position, the security
system will arm itself and lock the doors about 20
seconds after you turn the engine of{, remove the
key from the ignition, and close the hatch or trunk,
the hood (if equipped with the optional hood
switch), or last door. lf a door is opened during the
2o-second exit delay time, the timer will reset. The
remote control transmitter can still be used to arm
the system in the Auto Lock position.
Triggering the Alarm
After the security system is armed, the sound ot
breaking glass or the opening of a door, hood,
hatch or trunk will trigger the alarm, and cause
the following:
r The horn will sound for30 seconds.
The optional siren will sound lor 60 seconds.
. The parking lights will flash.
. The security indicator LED will flash twice per
second.
. The starter will be disabled.
At the end of the alarm cycle, the system will
automatically rearm.
Disarming the Security System
There are two ways to disarm the security system:
. With the transmitter
o With the disarm/valet switch
When the system is disarmed, regardless of the
method used, the parking lights will flash two times if
the alarm has not been triggered and three times if
the alarm has been triggered. To disarm the system
with the transmitter, press the unlock button (if the
system is in the beep sound mode, the horn will
sound two times if the alarm has not been triggered,
however, will sound three times if the alarm has
been triggered). The driver's door will unlock
(pressing the unlock button twice will unlock all
doors).
To disarm the security system using the
disarm/valet switch, enter the car and turn the
ignition switch to ON (ll) then press the disarm/valet
switch button. lf you open the door when the control
unit switch is in Auto or Auto Lock, a 2o-second
entry delay will give you time to disarm the system.
However, when the system is armed by the
transmitter, the entry delay time is changed to zero
seconds, and the alarm is triggered as soon as you
oDen the door.
ldentifying Tripped Sensors
The system will indicate the sensor which triggered
the alarm through the security indicator LED. While
sitting inside the vehicle wlth the key out of the
ignition switch, all doors, the hood (if equipped with
the optional hood swilch), the hatch or trunk must be
closed. Press and hold the disarm/valet switch.
Press the lock button and then the unlock button of
the transmitter. Belease the disarm/valet switch. The
status LED will blink according to the following code:
Sensors
Door
Trunk/Hatch
System Switches
Glass Breakage
Hood (Optional)
Number ol Flashes
1 blink, pause, repeat
2 blinks, pause, repeat
3 blinks, pause, repeat
4 blinks, pause, repeat
5 blinks, pause, repeat

see the security system owner's manual.
