Gaskets, seals and O-rings should be replaced any time the A/T 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.

Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
Refer to .

After overhaul, refill the A/T with new ATF.

When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter 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 7 , "
Changing A/T Fluid" , AT- 1 6 , "Checking A/T Fluid" .
Service Notice or PrecautionsUCS005M4
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning pro-
cedure. For radiator replacement, refer to Refer to CO-11, "
RADIATOR" .
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:

External leaks in the hub weld area.

Converter hub is scored or damaged.

Converter pilot is broken, damaged or fits poorly into crankshaft.

Steel particles are found after flushing the cooler and cooler lines.

Pump is damaged or steel particles are found in the converter.

Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)

Converter is contaminated with engine coolant containing antifreeze.

Internal malfunction of stator roller clutch.

Heavy clutch debris due to overheating (blue converter).

Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:

The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.

The threads in one or more of the converter bolt holes are damaged.

A/T malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.

Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006NT
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WA RN ING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemEFS006J2

Refill using recommended brake fluid. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted sur-
faces of body immediately wipe it off with cloth and then wash it away with water.

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use a flare nut wrench when removing a brake tube and use a
flare nut torque wrench when installing a brake tube.

When installing brake tubes and hoses, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or the bat-
tery cable from the negative terminal.

Burnish the new braking surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer toBR-29, "

Precautions for Brake System EFS006L8
CAUTION:

Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.

To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.

Use flare nut wrench when removing and installing brake
tube.

If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.

Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.

NOTE:
The gear ratio is set for every position separately.
“D” POSITION
Shifting over all the ranges of gear ratios from the lowest to the high-
est.
OVERDRIVE-OFF MODE
Use this position for the improved engine braking.
“L” POSITION
By limiting the gear range to the lowest position, the strong driving
force and the engine brake can be secured.
DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)
When downhill is detected with the accelerator pedal released, the engine brake will be strengthened up by
downshifting so as not to accelerate the vehicle more than necessary.
ACCELERATION CONTROL
According to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-
ing scene are judged. This function assists improvement in acceleration feeling by making the engine speed
proportionate to the vehicle speed. And a shift map which can gain a larger driving force is available for com-
patibility of mileage with driveability.
