Service Notice
Before proceeding with disassembly, thoroughly
clean the outside of the transmission. It is important to prevent the internal parts from becoming
contaminated by dirt or other foreign matter.
Disassembly should be done in a clean work
area.
Use lint-free cloth 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 assembly.
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.
When connecting AIT control unit harness
connector, tighten bolt until red projection is inline with connector.
The valve body contains precision parts and
requires extreme care when parts are removed
and serviced. Place disassembled valve body
parts in order, on a parts rack, 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 their bores in the valve body
under their own weight.
Before assembly, apply a coat of recommended
ATF to all parts. Apply petroleum jelly to protect
O-ring 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.
Flash or replace ATF cooler if excessive foreign
material is found in oil pan or clogging strainer.
Refer to TROUBLE DIAGNOSES Remarks,
AT-17.
After overhaul, refill the transmission with new
ATF.
When the AIT drain plug is removed, only some
of the fluid is drained. Old AIT fluid will remain
in torque converter and ATF cooling system.
Always follow the procedures under "Changing
AIT Fluid" in the MA section when changing AIT
fluid.

PREPARATION AND PRECAUTIONS
Supplemental Restraint System (SRS) "AIR
BAG"
The Supplemental Restraint System "Air Bag", used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and on the instrument panel on the pas- 6
0
senger side), sensors, a diagnosis unit, warning lamp, wiring harness and spiral cable. Information necessary
to service the system safely is included in the RS section of this Service Manual.
rI:',' '.i
WARNING:
To avoid renderlng the SRS Inoperative, whlch could increase the risk of personal injury or death
in the event of a colllslon which would result in alr bag Inflatlon, all malntenance must be performed
3:i
by an authorized NISSAN dealer.
Improper maintenance, Including Incorrect removal and lnstallatlon of the SRS, can lead to personal injury caused by unintentlonal activatlon of the system.
Do not use electrical test equipment o n any circuit related to the SRS unless instructed to in this [ :;
Service Manual. SRS wiring harnesses are covered wlth yellow insulatlon elther just before the
harness connectors or for the complete harness, for easy identiflcatlon.

DESCRIPTION
Shift Mechanism
The RE4R03A and RE4ROlA automatic transmissions use compact, dual planetafy gear systems to improve
power-transmission efficiency, simplify construction and reduce weight.
They also employ an optimum shift control and supelwide gear ratios. These improve starting performance
and acceleration during medium and high-speed operation.
Two one-way clutches are also employed: one is used for the forward clutch and the other for the low clutch.
These one-way clutches, combined with four accumulators, reduce shifting shock to a minimum.

TROUBLE DIAGNOSES
Remarks
FAIL-SAFE
The Arr control unit has an electronic Fail-safe (limp home mode). This allows the vehicle to be driven even
if a major electrical inpuVoutput device circuit is damaged.
Under Fail-safe. the vehicle always runs in third gear with shift lever position of 1, 2 or D. Customer may say ''I
"Sluggish, poor acceleration".
When Fail-safe operation occurs the next time the key is turned to the ON position, the Aff CHECK indica- ,;;
tor lamp will blink for about 8 seconds. (For diagnosis, refer to AT-24.)
Fail-safe may activate without electrical circuit damages if the vehicle is driven under extreme conditions (such
as excessive wheel spins and emergency braking immediately afterwards). In this case, turn key OFF for 5
seconds and then ON to recover normal shift pattern.
The blinking of the Aff CHECK indicator lamp for about 8 seconds will appear only once and be cleared. The
,~ customer may resume normal driving conditions by chance.
L .:
Always follow the "WORK FLOW' (Refer to AT-13).
The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate the damage of the vehicle speed sensor or the revolution sen- E:;
sor.
During the next SELF-DIAGNOSIS performed after checking the sensor, no damages will be indicated.

VG30DENG30DEl-r engine (RE4ROINRE4R03A) ... fin type cooler
Replace radiator lower tank (which includes ATF cooler) with a new one and flush cooler line using cleaning solvent and compressed air.
OED-ll SELF-DIAGNOSIS
PJT self-diagnosis is performed by the NT control unit in combination with the ECM. The results can be
read through the blinking pattern of t h e m CHECK indicator or the malfunction indicator lamp (MIL). Refer
to the table on AT43 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 WT control
unit memories.
Always perform the procedure "HOW TO ERASE DTC" on AT48 to complete the repalr and avoid
unnecessary blinklng of the MIL.
The following self-diagnostic items can be detected using ECM self-diagnostic results mode' only when
the AT CHECK indicator lamp does not indicate any malfunctions.
-Improper shifting to 1st 2nd, 3rd, or 4th gear position
-Improper torque converter clutch operation.

TROUBLE DIAGNOSES
Diagnosis by CONSULT
NOTICE
1. The CONSULT electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the CONSULT display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT and that indicated in Service Manual
may differ slightly. This occurs because of the following reasons:
Actual shift schedule has more or less tolerance or allowance,
Shift schedule indicated in Service Manual refers to the point where shifts start, and gear position displayed on CONSULT indicates the point where shifts are completed.
3. Shift solenoid valve "A'or "€3" is displayed on CONSULT at the start of shifting. Gear position is displayed
upon completion of shifting (which is computed by AiT control unit).
4. Additional CONSULT information can be found in the Operation Manual supplied with the CONSULT unit.

STALL TESTING
Stall test procedure
1. Check AIT and engine fluid levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes until engine oil and ATF
reach operating temperature.
ATF operatlng temperature:
50 - 80°C (122 - 176°F)
3.
4.
Set parking brake and block wheels.
Install a tachometer where it can be seen by driver during test.
it is good practlce to put a mark on polnt of specified
englne speed on Indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.
6. Accelerate to wide-open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
During test, never hold throttle wide-open for more than 5
seconds.
Stall revolution:
2,300 - 2,500 rpm (RE4ROlA)
2,930 - 3,180 rpm (RE4R03A)
8. Move selector lever to “N”.
9. Cool off ATF.
Run engine at idle for at least one minute.
10. Repeat steps 5 through 9 with selector lever in “2”, “1” and “R”
positions.
JUDGEMENT OF STALL TEST
The test result and possible damaged components relating to each result are shown in the illustration.
In order to pinpoint the possible damaged components, follow the WORK FLOW shown in AT-13.
Note
Stall revolution is too hlgh in “D” or “2’ positlon:
Slippage occurs in 1st gear but not in 2nd and 3rd gears. ..... Low one-way clutch slippage
Slippage occurs in the following cases:
1) 1st through 3rd gears in “D” position and engine brake functions with power shift switch set to “POWER’.
2) 1st and 2nd gears in “2” position and engine brake functions with accelerator pedal completely released
(fully closed throttle). ..___
Forward clutch or forward one-way clutch slippage
Stall revolution is too high In “R” position:
Engine brake does not function in “1” position. ...._Low 8 reverse brake slippage
Engine brake functions in “ I ” position. _....Reverse clutch slippage
Stall revolution within speclficatlons:
Vehicle does not achieve speed of more than 80 km/h (50 MPH). ..... One-way clutch seizure in torque
converter housing
CAUTION:
Be careful since automatic fluid temperature increases abnormally.
Slippage occurs in 3rd and 4th gears in “D” position. __...High clutch slippage
Slippage occurs in 2nd and 4th gear in “D’ position. ..... Brake band slippage
Stall revolution less than specifications:
Poor acceleration during starts. ..... One-way clutch seizure in torque converter

TROUBLE DIAGNOSES - A / l Shift Lock System
Description
The mechanical key interlock mechanism also operates as a
shift lock:
With the key switch turned to "ON", the selector lever cannot
be shifted from "P" (parking) to any other position unless the
brake pedal is depressed.
With the key removed, the selector lever cannot be shifted
from "P" to any other position.
The key cannot be removed unless the selector lever is placed
in "P".
The shift lock and key interlock mechanisms are controlled by
the ON-OFF operation of the shift lock solenoid and by the
operation of the rotator and slider located inside the key
cylinder, respectively.
