e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T
fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the A/T fluid temperature approximately 65°C (149°F).
NOTE:
A/T fluid level will be greatly affected by temperature as shown in the figure. Therefore, be certain
to perform operation while checking data with CONSULT-III.
a. Select “DATA MONITOR”.
b. Read out the value of “ATF TEMP 1”.
7. Re-check A/T fluid level at A/T fluid temperatures of approximately 65°C (149°F) using “HOT” range on A/
T fluid level gauge.
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

To check A/T fluid level, insert the A/T fluid level gauge
until the cap contacts the end of the A/T fluid charging
pipe, with the A/T fluid level gauge rotated from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.

If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-13,
"RADIATOR" and AT- 1 4 , "A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.

TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
How to Perform Trouble Diagnosis for Quick and Accurate RepairNCS00021
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor (throttle position sensor) or PNP switch and
provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a error that occurs intermittently
rather than continuously. Most intermittent errors are caused by poor
electric connections or improper wiring. In this case, careful check-
ing of suspected circuits may help prevent the replacement of good
parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-III (or GST) or a circuit tester connected should be
performed. Follow the AT- 4 3 , "
WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” as
shown on the example (Refer to AT- 4 4
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
