CAUTION: When fasteners are removed, always
reinstall them at a the same location from which
they were removed. If a fastener needs to be
replaced, use the correct part number fastener for
that application. If the correct part number fastener
is not available, a fastener of equal size and
strength (or stronger) may be used. Fasteners that
are not reused, and those requiring thread locking
compound, will be called out. The correct torque
values must be used when installing fasteners that
require torque. If the above conditions are not
followed, parts or system damage could result.

AUTOMATIC TRANSMISSION (AW30-40LE) 7A–7
CONTROL AND FUNCTIONS
Item Description
Shift and lock-up control • In D range, speed change point and Lock-up point can be changed by
setting pattern selection switch to "POWER", "NORMAL" or "WINTER"
mode.
• Gear shift position in the conditions made up of transmission shift positions
(D.2.L) combined with pattern selection switch (POWER, NORMAL, and
WINTER) can be controlled in accordance with vehicle speed and the
opening of throttle valve.
Overdrive cut control • If O/D OFF switch is set on in D range (O/D OFF lamp ON), gear shift to O/
D is not effected.
• Overdrive is released at O/D OFF switch on and high transmission oil
temperature (More than 130
C).
However, to prevent engine over revolution
•4
3 shifting at vehicle speed is less than 118 km/h.
•3
4 shifting at vehicle speed is more than 131 km/h.
Lock-up cut control • In D range, 3rd or O/D lock-up is conducted in "POWER" or "NORMAL"
mode.
• In 2, L range, lock-up is off in the whole area.
• Lock-up timing is controlled to reduce gear shift shock using kind of gear
shift (shift up, etc.) lock-up status at the time of gear shift judgement, gear
step and throttle opening after gear shift.
• Lock-up is released at brake on or high transmission oil temperature (More
than 130
C).
• Lock-up is prohibited when idling is defected by throttle position sensor.
Driving mode select control • The TCM selects a suitable driving mode from the nine kinds for the variety
driving condition.
i) Economy mode ii) Power mode iii) Winter mode iv) HOT1 mode v) HOT2
mode vi) L4 mode vii) Slope mode (Up slope 1, Up slope 2 and Down
slope mode)
• The priority of driving mode:
Economy < Power < Slope < L4 < Winter < HOT1 < HOT2
Squat control • When the TCM detects D signal on, the TCM controls 1–3–1 shift by
setting a timer, in order to improve the shift feel at N
D.
Line pressure control • The TCM output current which corresponds to throttle oil pressure to
pressure control solenoid based on throttle opening.
Indicate oil temperature warning
function• If the transmission oil temperature sensor senses that transmission oil
temperature is greater than 146
C, the TCM turn on A/T OIL TEMP
warning lamp. (The warning lamp is turned off, if oil temperature is less
than 126
C.)
L4 mode control • The TCM judges whether the transfer is engaged in high or low based on
the ratio rpm data from output speed sensor in the transmission and the
rpm data from speed meter sensor to select the shift map.
Up and down hill control • The TCM judges up and down hill, and change shift pattern based on
throttle opening and acceleration.
Correct oil temperature control • If the temperature exceeds a predetermined value, the TCM selects the
high oil temperature shift point for downshifting, thus preventing the oil
temperature from rising. (More than 130
C, D range)

MAJOR INPUT/OUTPUT COMPONENTS
Component Function
Input
Vehicle speed sensor (Speedometer) Detects the vehicle speed (Back-up sensor of output
revolution sensor).
Output revolution sensor (Transmission) Detects the vehicle speed.
Input revolution sensor (Transmission) Detects the input revolution (O/D direct clutch drum
revolution).
Engine revolution sensor Detects the engine revolution.
Throttle position sensor Detects the throttle opening rate.
Neutral start switch Detects the select lever position.
Pattern select switch Detects whether the driver has selected "NORMAL",
"POWER", or "WINTER" mode.
Overdrive off switch Detects whether the driver has selected O/D.
Brake lamp switch Detects whether the driver has pressed the brake pedal or
not.
Oil temperature sensor Detects the oil temperature.
Diagnostic star t switch Star ts self-diagnosis and displays a code for faulty part if
any.
Input/Output
Data link connector When connected with Tech2 or tester, can communicate
the data for function check, etc.
Output
Shift solenoid S1, S2 Selects shift point and gear position suited to the vehicle
running condition on the basis of TCM output.
Lock-up control solenoid SL Control the lock-up clutch suited to the vehicle running
condition on the basis of TCM output.
Pressure control solenoid STH Adjusts throttle pressure by energizing current of linear
pressure control solenoid to prevent the shift shock and to
obtain shift smoothly.
"CHECK TRANS" lamp When trouble has occurred to throttle position sensor,
vehicle speed sensor, or solenoid, "CHECK TRANS" lamp
is blinked to warn the driver. If also displays the trouble
code.
A/T OIL TEMP warning lamp Lights when ATF oil temperature rises. (Turned on at
greater than 146
C . Turned off at less than 126C.
Power mode lamp Informs the driver whether the vehicle is in power mode or
not.
Winter mode lamp Informs the driver whether the vehicle is in winter mode or
not.
Computer
Transmission Control Module (TCM) Based on the signal from each switch and sensors, judges
necessary shift point and lock-up operation, and send
signal to each solenoid.

SPEED CHANGE AND LOCK-UP PATTERN
If you select a speed range and a lock-up pattern as shown below by specifying respective positions of transmission
shift lever, transfer shift lever and pattern select switch, the transmission control computer controls speed change and
lock-up operations based on the specified pattern in accordance with the degree of throttle opening and vehicle speed.

: The lock-up operation is available.
( ): Transmission is shifted at high speed to prevent overrun.
