Checking A/T FluidNJAT02281. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in ªPº position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of
either range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side of
range, add fluid to the charging pipe.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80ÉC (122
to 176ÉF) using ªHOTº range on dipstick.
SMA853B
6. Check fluid condition.
+If fluid is very dark or smells burned, refer to AT section for
checking 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 LC-16, ªRadia-
torº.
SMA027D
Changing A/T FluidNJAT02291. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid.
Always refill same volume with drained fluid.
Fluid grade:
Nissan Matic ªDº or Genuine Nissan Automatic
Transmission Fluid. Refer to ªRECOMMENDED FLU-
IDS AND LUBRICANTSº, MA-16.
Fluid capacity (With torque converter):
7.0!(6-1/8 Imp qt)
Drain plug:
: 29 - 39 N´m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to ªChecking A/T Fluidº.
If fluid is still dirty, repeat steps 2 through 5.

3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.
+It is good practice to mark the point of specified engine
rpm 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:
QG13DE 2,000 - 2,300 rpm
QG15DE 2,000 - 2,300 rpm
QG16DE 2,200 - 2,700 rpm

8. Move selector lever to ªNº position.
9. Cool off ATF.
+Run engine at idle for at least one minute.
10. Repeat steps 5 through 9 with selector lever in ª2º, ª1º and ªRº
positions.
JUDGEMENT OF STALL TESTNJAT0026S02The test result and possible damaged components relating to each
result are shown in the illustrations on next page.
In order to pinpoint the possible damaged components, follow the
WORK FLOW shown in AT-73 (Except for Euro-OBD) or AT-78
(EURO-OBD).
NOTE:
Stall revolution is too high in ªDº, ª2º or ª1º position:
+Slippage occurs in 1st gear but not in 2nd and 3rd gears. .....
Low one-way clutch slippage
+Slippage occurs in the following gears:

DescriptionNJAT0102+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 ªPº (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from ªPº to any other position.
The key cannot be removed unless the selector lever is placed in ªPº.
+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.
