Revision: 2007 April2007 M35/M45

Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
AT- 9 , "
ATF COOLER SERVICE" .

After overhaul, refill the transmission with new ATF.

When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT- 1 2 , "
Changing A/T Fluid" , AT- 1 3 , "Checking A/T Fluid" .
Service Notice or PrecautionsNCS001JF
ATF COOLER SERVICE
If ATF contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to AT- 1 4 , "
A/T
Fluid Cooler Cleaning" . For radiator replacement, refer to CO-14, "RADIATOR" (for VQ35DE engine), CO-43,
"RADIATOR" (for VK45DE engine).
OBD-II SELF-DIAGNOSIS

A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table
on AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" for the indicator used to display each self-diagnostic
result.

The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure on AT- 4 1 , "
HOW TO ERASE DTC" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-54, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VQ35DE engine), EC-
756, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VK45DE engine).

Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For description and how to disconnect, refer to PG-104, "
HAR-
NESS CONNECTOR" .

AT-14
A/T FLUID
Revision: 2007 April2007 M35/M45
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 reversed 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 A/T fluid 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-14,
"RADIATOR" (for VQ35DE engine), CO-43, "RADIATOR"
(for VK45DE engine) 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.
10. Tighten level gauge bolt.
A/T Fluid Cooler CleaningNCS001JK
Whenever an A/T is replaced, the A/T fluid cooler mounted in the radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of ATF. In either case, mal-
function of the newly serviced A/T may result.
Debris, if present, may build up as ATF enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE
1. Position an oil pan under the A/T inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the A/T fluid cooler inlet and outlet rubber hoses
from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any ATF that remains in the cooler hoses to drain into the
oil pan.Level gauge bolt

A/T FLUID CHECK
A/T Fluid Leakage and A/T Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 3 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/
T fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Engine start, apply foot brake, and place selector lever in “D”
position.
