LASER BEAM AIMING ADJUSTMENT
Revision: 2006 January2006 M35/M45
2. Adjust the height of the target board with aligning the upside tip
of the triangle scale with the center of laser beam axis.
NOTE:
The center of laser beam axis is located at 92 mm (3.62 in) from
the right edge and 22 mm (0.87 in) from the top of the ICC sen-
sor integrated unit from a front view of vehicle.
ADJUSTING THE RIGHT-LEFT POSITION OF THE TARGET
1. Attach a scale [at least 350 mm (14 in) or longer] or stick as
shown in the figure.
2. Suspend a thread with weight on the tip of the thread to 266 mm
(10.47 in) right side of the target board from the center of the
target board on top.
SETTING THE TARGET
1. Suspend a thread with weight on tip to splice the center of the front and rear bumpers. Then, mark the
center point on the ground as each weight points.
2. Link the front and rear bumpers center points marked on the ground, and mark a point 3.9 m (12.8 ft)
ahead of the front bumper, on the extended line of the previous link line of the bumper center points.
Then, adjust the position of the target board so that the weight come on the top of the marked point [3.9 m
(12.8 ft) ahead of the front bumper] and face to the vehicle.

3. Adjust the position of the target board so that the extended line
that links the center of the rear window glass (the center of the
rear window defogger pattern) and the center of the windshield
(the setting part of the room mirror) align with the weight sus-
pended from the board.
4. Remove the thread suspended to the right side of board and
suspend a thread with weight on tip on the center of the target
board. Then mark the point of weight on the ground.
5. Pivot the edge of the target board 25
to either side.
NOTE:
Approx. 90 mm (3.54 in) shift rates the 25
movement.
NOTE:
The distance between center of laser beam axis and target board is 4 m (13 ft).
6. Do not place anything in the space shown in the figure (view from top).
NOTE:
In case the space shown in the figure is not available, make a space by covering the side of the target
board with a 1400 mm (4.6 ft)-size frosted black board or black cloth.

PRECAUTIONS
Revision: 2006 January2006 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.

A/T CONTROL SYSTEM
Revision: 2006 January2006 M35/M45
Shift MechanismNCS001JO
The A/T uses compact triple planetary gear systems to improve power transmission efficiency, simplify con-
struction and reduce weight.
It also employs an optimum shift control and super wide gear ratios. They improve starting performance and
acceleration during medium and high-speed operation.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite to the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2
-16
ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electrical scale or of quality recycle/recharge equipment.

1. Check the clearance and the surface height between the hood and each part by visual and tactile feeling.
(Fitting standard dimension in the table below should be satisfied.)
* Unit: mm (in)
2. In case out of specification, adjust them according to the procedures shown below.
3. Remove the hood lock and adjust the height by rotating the
bumper rubber until the hood becomes 1 to1.5 mm (0.04 to
0.059 in) lower than the fender.
4. Temporarily tighten the hood lock, and position by engaging it with the hood striker. Check the lock and
striker for looseness and adjust the clearance and evenness by the striker to satisfy the specification.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or the hood pressed lightly (approx. 29 N (3 kg)).
6. After adjustment tighten lock bolts to the specified torque.

REMOVAL
1. Support the hood lock assembly with a proper material to pre-
vent it from falling.
WAR NING :
Body injury may occur if no supporting rod is holding the
hood open when removing the hood stay.
2. Remove stud balls on the hood stays at the hood side.
3. Remove the hinge mounting nuts on the hood to remove the
hood assembly.
CAUTION:
Operate with two workers, because of its heavy weight.

CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Check that the secondary latch is properly engaged with the secondary striker (B: 6.8 mm (0.268 in)
shown in the figure) with hood's own weight.
2. While operating the hood opener, carefully check that the front end of the hood is raised by approx. 20
mm (0.79 in). Also check that the hood opener returns to the original position.
3. Check that the hood opener operating is 294 N (30 kg) or below.
4. Install as static closing face of hood is 392 – 441 Nꞏm (35– 44 kg-m).
5. Check the hood lock lubrication condition. If necessary, apply
“body grease” to the points shown in the figure.
