PRECAUTIONS
Revision: 2007 April2007 M35/M45
Precautions NCS001JE
Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.
When removing the transmission from a vehicle, do not use the
companion flange section at the rear end of the transmission as
a support point. (VK45DE models only)
Always use the specified brand of ATF. Refer to MA-12, "Fluids
and Lubricants" .
Use lint-free paper not cloth rags during work.
After replacing the ATF, dispose of the waste oil using the meth-
ods prescribed by law, ordinance, etc.
Before proceeding with disassembly, thoroughly clean the out-
side of the transmission. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign mat-
ter.
Disassembly should be done in a clean work area.
Use lint-free paper or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation
of the transmission.
Place disassembled parts in order for easier and proper assem-
bly.
All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
Gaskets, seals and O-rings should be replaced any time the
transmission is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

DTC P0615 START SIGNAL CIRCUIT
Revision: 2007 April2007 M35/M45
TCM terminals and data are reference value. Measured between each terminal and ground.
Diagnostic ProcedureNCS001KV
1. CHECK STARTER RELAY
With CONSULT-II
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “A/T” with CONSULT-II and check monitor “STARTER
RELAY” ON/OFF.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between the IPDM E/R connector and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK HARNESS BETWEEN A/T ASSEMBLY HARNESS CONNECTOR AND IPDM E/R CONNEC-
TOR
1. Turn ignition switch OFF.
2. Disconnect A/T assembly harness connector and IPDM E/R connector.
3. Check continuity between A/T assembly harness connector and
IPDM E/R connector.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.

A/T FLUID TEMPERATURE SENSOR 2 REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery cable from the negative terminal.
2. Drain ATF through drain plug.
3. Disconnect heated oxygen sensor 2 harness connector.
4. Remove oil pan, oil pan gasket and clips (VQ35DE models) or oil pan, oil pan gasket, brackets and clips
(VK45DE models) according to the following procedures.
a. VQ35DE models
i. Remove clips (1).
ii. Remove oil pan (2) and oil pan gasket.

b. VK45DE models
i. Remove clips (1) and brackets (2).
ii. Remove oil pan (3) and oil pan gasket.
: Front
: Bolt (22)
5. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
6. Disconnect A/T fluid temperature sensor 2 connector.
CAUTION:
Be careful not to damage connector.
