6. Wipe fluid off the CVT fluid level gauge. Then rotate the CVT
fluid level gauge 180° and re-insert it into the CVT charging pipe
as far as it will go.
CAUTION:
Always use lint free paper towels to wipe fluid off the CVT
fluid level gauge.
7. Remove the CVT fluid level gauge and check that the fluid level
is within the specified range as shown. If the fluid level is at or
below the low side of the range, add the necessary specified
NISSAN CVT fluid through the CVT charging pipe.
CAUTION:

Only use specified NISSAN CVT fluid.

Do not overfill the CVT.
8. Install the CVT fluid level gauge to the CVT fluid charging pipe until it locks.
CAUTION:
When CVT fluid level gauge is installed into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place.

2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and
refill with new specified NISSAN CVT fluid in the CVT fluid
charging pipe with the engine running at idle speed.
CAUTION:
Only use the specified NISSAN CVT fluid.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose [outlet side (1)].

from select lever (3).
5. Shift control lever to neutral position.
6. Remove control lever knob.
7. Remove center console assembly. Refer to IP-22, "
CENTER
CONSOLE ASSEMBLY" .
8. Remove control device assembly bolts.
9. Remove exhaust front tube, center muffler and heat plate. Refer
to EX-4, "
Removal and Installation" .
10. Remove cable support bracket.
11. Remove select cable and shift cable from cable bracket.
12. Remove control device assembly from the vehicle.
INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Self tapping bolts are used to attach cables to the clutch housing.

Securely assemble each cable and lever of control shaft.

Be careful about the installation direction, and push control lever
knob onto control lever.
CAUTION:
Do not reuse control lever knob.

Make sure that the front/rear claws (1) of control device assem-
bly are in contact with flange of the floor (2).

When control lever is selected to 1st-2nd side and 5th-6th side,
confirm control lever returns to neutral position smoothly.

When control lever is shifted to each position, make sure there
is no binding or disconnection in each boot.

Move stopper (1) to lock position when installing the shift cable
onto the shift lever.
