If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis
In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
However, this information is erased by turning ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-III.

Revision: 2006 November2007 350Z
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS0003I
Torque converter clutch solenoid valve is activated, with the gear in D4 , D5 , M2 , M3 , M4 and M5 by the
TCM in response to signals sent from the vehicle speed sensor and accelerator pedal position sensor
(throttle position sensor). Torque converter clutch 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 1.0/8) in lock-up condition, the engine speed should
not change abruptly. If there is a big jump in engine speed, there is no lock-up.
CONSULT-III Reference ValueNCS0003J
On Board Diagnosis LogicNCS0003K
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-III or 3rd judgment flicker without
CONSULT-III is detected under the following conditions.
–When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–When TCM detects as irregular by comparing target value with monitor value.
Possible CauseNCS0003L
Torque converter clutch solenoid valve
Harness or connectors
(Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureNCS0003M
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ACCELE POSI” and “SLCT LVR POSI”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VHCL/S SE-A/T: 80 km/h (50 MPH) or more
ACCELE POSI: 0.5/8 – 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected go to AT- 1 2 6 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.

DTC P0744 A/T TCC S/V FUNCTION (LOCK-UP)PFP:31940
DescriptionNCS0003O
This malfunction is detected when the A/T does not shift into 5th gear position or the torque converter clutch
does not lock-up as instructed by the TCM. This is not only caused by electrical malfunction (circuits open or
shorted) but also by mechanical malfunction such as control valve sticking, improper solenoid valve operation,
etc.
CONSULT-III Reference ValueNCS0003P
On Board Diagnosis LogicNCS0003Q
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P0744 A/T TCC S/V FNCTN” with CONSULT-III or 3rd judgment flicker without
CONSULT-III is detected under the following conditions.
–When A/T cannot perform lock-up even if electrical circuit is good.
–When TCM detects as irregular by comparing difference value with slip rotation.
Possible CauseNCS0003R
Harness or connectors
(Solenoid circuit is open or shorted.)
Torque converter clutch solenoid valve
Hydraulic control circuit
DTC Confirmation ProcedureNCS0003S
CAUTION:
Always drive vehicle at a safe speed.

If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine.
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Drive vehicle and maintain the following conditions for at least 30 consecutive seconds.
ACCELE POSI: More than 1.0/8
SLCT LVR POSI: “D” position

SHIFT CONTROL SYSTEM
Revision: 2006 November2007 350Z
REMOVAL
1. Disconnect lower lever of control device and control rod.
2. Remove manual lever from A/T.
3. Remove control rod from vehicle.
INSTALLATION
Note the following, and install in the reverse order of removal.
After installation is completed, adjust and check A/T position. Refer to AT- 2 0 6 , "Adjustment of A/T Posi-
tion" and AT- 2 0 6 , "Checking of A/T Position" .
Adjustment of A/T PositionNCS0008U
1. Loosen nut of control rod.
2. Place PNP switch and selector lever in “P” position.
3. While pressing lower lever toward rear of vehicle (in “P” position
direction), tighten nut to the specified torque. Refer toAT- 2 0 5 ,
"CONTROL ROD COMPONENTS"
Checking of A/T PositionNCS0008V
1. Place selector lever in “P” position, and turn ignition switch ON.
2. Make sure that selector lever can be shifted to other than “P” position when brake pedal is depressed.
Also make sure that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Make sure that transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination
meter.
Shift selector lever to “+” and “-” sides, and check that set shift position changes.
