Check CVT fluid condition.
• If CVT fluid is very dark or smells burned, check operation of CVT.

Flush cooling system after repair of CVT.

• If CVT fluid contains frictional material (clutches, brakes, etc.),

replace radiator and flush cooler line using cleaning solvent and
compressed air after repair of CVT. Refer to

CO-34, "Exploded

View"

.

Changing

INFOID:0000000000988984

1.

Remove drain plug, and then drain CVT fluid from oil pan.

2.

Install drain plug to oil pan.

CAUTION:

Never reuse drain plug gasket.

3.

Fill CVT fluid from CVT fluid charging pipe to the specified level.

4.

With the engine warmed up, drive the vehicle in an urban area. When ambient temperature is 20

°

C

(68

°

F), it takes about 10 minutes for the CVT fluid to warm up to 50 to 80

°

C (122 to 176

°

F).

5.

Check CVT fluid level and condition.

6.

Repeat steps 1 to 5 if CVT fluid has been contaminated.

CAUTION:

• Use only Genuine NISSAN CVT Fluid NS-2. Never mix with other fluid.
• Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and CVT

durability, and may damage the CVT, which is not covered by the warranty.

• When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
• Sufficiently shake the container of CVT fluid before using.
• Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid.

Fluid status

Conceivable cause

Required operation

Varnished (viscous

CVT fluid become
degraded due to
high temperatures.

Replace the CVT fluid and check the
CVT main unit and the vehicle for
malfunctions (wire harnesses, cool-
er pipes, etc.)

Milky white or

Water in the fluid

Replace the CVT fluid and check for
places where water is getting in.

Replace the CVT fluid and check for
improper operation of the CVT.

STALL TEST

STALL TEST

Inspection and Judgment

INFOID:0000000000914702

INSPECTION

1.

Inspect the amount of engine oil. Replenish the engine oil if necessary.

2.

Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80

°

C (122 to 176

°

F). Inspect the

amount of CVT fluid. Replenish if necessary.

3.

Securely engage the parking brake so that the tires do not turn.

4.

Install a tachometer where it can be seen by driver during test.
NOTE:
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.

While holding down the foot brake, gradually press down the
accelerator pedal.

7.

Quickly read off the stall speed, and then quickly remove your
foot from the accelerator pedal.

CAUTION:

Never hold down the accelerator pedal for more than 5 sec-
onds during this test.

8.

Move the selector lever to the “N” position.

9.

Cool down the CVT fluid.

CAUTION:

Run the engine at idle for at least 1 minute.

10. Repeat steps 6 through 9 with selector lever in “R” position.

INSPECTION

Line Pressure Test Procedure

1.

Inspect the amount of engine oil and replenish if necessary.

2.

Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80

°

C

(122 to 176

°

F), then inspect the amount of CVT fluid and replenish if necessary.

NOTE:
The CVT fluid temperature rises in the range of 50 to 80

°

C (122 to 176

°

F) during 10 minutes of driv-

ing.

3.

After warming up CVT, remove the oil pressure detection plug
(A) and install the oil pressure gauge (commercial service tool).

CAUTION:

When using the oil pressure gauge, be sure to use the O-
ring attached to the oil pressure detection plug.

4.

Securely engage the parking brake so that the tires do not turn.

5.

Start the engine, and then measure the line pressure at both idle
and the stall speed.

CAUTION:

• Keep the brake pedal pressed all the way down during

measurement.

• When measuring the line pressure at the stall speed, refer

to

TM-316, "Inspection and Judgment"

.

6.

After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque below.

CAUTION:

• Never reuse O-ring.
• Apply CVT fluid to O-ring.
