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-13, "
Exploded
View".
ChangingINFOID:0000000003849077
CAUTION:
Replace O-ring with new ones at the final stage of the operation when installing.
1. Remove drain plug from oil pan.
2. Remove drain plug gasket from drain plug.
3. Install drain plug gasket to drain plug.
CAUTION:
Never reuse drain plug gasket.
4. Install drain plug to oil pan.
5. Fill CVT fluid from CVT fluid charging pipe to the specified level.
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. Refer to TM-37,
"CONSULT-III Function (TRANSMISSION)".
6. With the engine warmed up, drive the vehicle in an urban area.
NOTE:
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).
7. Check CVT fluid level and condition.
8. Repeat steps 1 to 5 if CVT fluid has been contaminated.

STALL TEST
STALL TEST
Inspection and JudgmentINFOID:0000000003849078
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 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 move selector lever to “D”
position.
6. Gradually press down accelerator pedal while holding down the
foot brake.
7. Quickly read off the stall speed, and then quickly remove your
foot from accelerator pedal.
CAUTION:
Never hold down accelerator pedal for more than 5 seconds
during this test.
8. Move selector lever to “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
and install the joint pipe adapter (SST: KV31103600), adapter
(SST: 25054000), oil pressure gauge set (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 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 brake pedal pressed all the way down during mea-
surement.
 When measuring the line pressure at the stall speed.
Refer to TM-144, "
Inspection and Judgment".
6. Install oil pressure detection plug and tighten to the specified
torque below after the measurements are complete.
CAUTION:
 Never reuse O-ring.
 Apply CVT fluid to O-ring.

Judgment Possible cause
Idle speedLow for all positions
(“P”, “R”, “N”, “D”, “L”)Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example
 Oil pump wear
 Pressure regulator valve or plug sticking or spring fatigue
 Oil strainer ⇒ oil pump ⇒ pressure regulator valve passage oil leak
 Engine idle speed too low
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
HighPossible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example
 Accelerator pedal position signal malfunction
 CVT fluid temperature sensor malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking in OFF state, filter
clog, cut line)
 Pressure regulator valve or plug sticking
Sta ll sp ee dLine pressure does not
rise higher than the line
pressure for idle.Possible causes include a sensor malfunction or malfunction in the pressure adjustment func-
tion.
For example
 Accelerator pedal position signal malfunction
TCM malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (shorting, sticking in ON
state)
 Pressure regulator valve or plug sticking
The pressure rises, but
does not enter the
standard position.Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example
 Accelerator pedal position signal malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking, filter clog)
 Pressure regulator valve or plug sticking
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
