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.

FUNCTION OF CLUTCH AND BRAKENJAT0013S03
Clutch and brake components Abbr. Function
5Reverse clutch R/C To transmit input power to front sun gear7.
6High clutch H/C To transmit input power to front planetary carrier10.
15Forward clutch F/C To connect front planetary carrier10with forward one-way clutch16.
17Overrun clutch O/C To connect front planetary carrier10with rear internal gear13.
4Brake band B/B To lock front sun gear7.
16Forward one-way clutch F/O.C When forward clutch15is engaged, to stop rear internal gear13from rotat-
ing in opposite direction against engine revolution.
18Low one-way clutch L/O.C To stop front planetary carrier10from rotating in opposite direction against
engine revolution.
19Low & reverse brake L & R/B To lock front planetary carrier10.

*1: Operates when overdrive control switch is set in ªOFFº position.
*2: Oil pressure is applied to both 2nd ªapplyº side and 3rd ªreleaseº side of band servo piston. However, brake band does not contract
because oil pressure area on the ªreleaseº side is greater than that on the ªapplyº side.
*3: Oil pressure is applied to 4th ªapplyº side in condition *2 above, and brake band contracts.
*4: A/T will not shift to 4th when overdrive control switch is set in ªOFFº position.
*5: Operates when overdrive control switch is ªOFFº.
j: Operates.
A: Operates when throttle opening is less than 3/16, activating engine brake.
B: Operates during ªprogressiveº acceleration.
C: Operates but does not affect power transmission.
D: Operates when throttle opening is less than 3/16, but does not affect engine brake.

+Forward one-way clutch
+Overrun clutch
+Low and reverse brakeAs overrun clutch engages, rear internal gear is locked by the operation of low and
reverse brake.
This is different from that of D
1and 21.
Engine brake Overrun clutch always engages, therefore engine brake can be obtained when
decelerating.

+Forward clutch

+Brake bandRear sun gear drives rear planetary carrier and combined front internal gear. Front internal gear now
rotates around front sun gear accompanying front planetary carrier.
As front planetary carrier transfers the power to rear internal gear through forward clutch and forward
one-way clutch, this rotation of rear internal gear increases the speed of rear planetary carrier com-
pared with that of the 1st speed.
