P0740 TORQUE CONVERTER
DescriptionINFOID:0000000005397310
• The torque converter clutch solenoid valve is activated, with the gear in D4 and D3, by the TCM in response
to signals sent from the output speed sensor and t he ECM (throttle opening). Lock-up piston operation will
then be controlled.
• Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
• When the accelerator pedal is depressed (less than 2/8) on lock-up condition, the engine speed should not
change abruptly. If there is an abrupt change in engine speed, there is no lock-up.

Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397312
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0740 T/C CLUTCH SOL” with CO NSULT-III or 7th judgement flicker without CON-
SULT-III is detected when TCM detects an improper vo ltage drop while it tries to operate solenoid valve.
Possible CauseINFOID:0000000005397313
• Torque converter clutch solenoid valve
• Harness or connector
(The solenoid circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005397314
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III and wait at least 1 second.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds. VEHICLE SPEED: 80 km/h (50 MPH) or more
THROTTLE POSI: 0.5/8 - 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehic le uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If the check result is NG, go to AT-125, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle in D
1→ D2→ D3→ D4→ D4 lock-up position.
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-125, "

DescriptionINFOID:0000000005397324
The line pressure solenoid valve regulates the oil pum p discharge pressure to suit the driving condition in
response to signals sent from the TCM.
The line pressure duty cycle value is not constant when the closed throttle po sition switch is ON. To
confirm the line pressure duty cycle at low-pressure, the accelerator (throttle) sh ould be open until the
closed throttle position switch is OFF.

WITH INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock:With the ignition knob switch turned to ON, selector lever cannot be shifted from “P” position to any other
position unless brake pedal is depressed.
With the ignition knob switch turned to OFF, selector lever cannot be shifted from “P” position to any other
position.
• The shift lock and key interlock mechanisms are contro lled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the i gnition knob switch, respectively.
WITHOUT INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are contro lled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside key cylinder, respectively.

REMOVAL AND INSTALLATION
Removal
1. Remove front drive shaft. Refer to FA X - 9.
2. Remove differential side oil seals using a suitable tool. CAUTION:
Be careful not to scratch transaxle case and converter
housing.
Installation
Installation is in the reverse order of removal.
NOTE:
• Drive each differential side oil seal evenly using Tools (Transaxlecase side only) and suitable tool (Convertor housing side only) so
that differential side oil seal prot rudes by the dimension (C) or (D)
respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)

bly.
CAUTION:
Set Tool directly over return springs.
5. Remove spring retainer assembly from transaxle case. CAUTION:
Do not remove return springs from spring retainer.
6. Apply compressed air into the oil hole on transaxle case as shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove low & reverse brake piston from transaxle case by turn- ing it.
8. Inspect transaxle case. Replace if damaged or worn.
9. Remove seal lip (1) and D-ring (2) from low & reverse brake pis- ton (3).
