ACTION
Refer to the Repair Flow Chart on page 2 for CVT repair.
Always handle the CVT and component assemblies carefully and with the
appropriate lifting tools.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. HINT: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

GENERAL INFORMATION

Precautions when Disassembling a CVT Assembly
Transmissions are vulnerable to particles (dust, metal, lint, etc.).
When disassembling a CVT, make sure your work environment (shop, workbench, etc.),
transmission area (sub-frame, oil pan, harness connector, etc.), and your hands are free of
contamination.
IMPORTANT:


Wash and clean the exterior of the CVT assembly prior to disassembling.
CAUTION: Cover all air breather and drive shaft holes to prevent water intrusion.



Refrigerating oil seals may help in assembly (axle and T/C seals).



Only disassemble those parts which are mentioned in this bulletin.



Make sure all parts are clean prior to assembling / installing.



Apply rust penetrant to locator / dowel pins on torque converter housing and side
cover of CVT and allow to soak as needed (Figure 6).

Figure 6


Unpack service parts just before
installation.



To aid with organization, store
related parts that have been
removed separately.

IMPORTANT: The CVT unit “wiring harness
connector” will be reused during this
procedure. The wiring harness can be
disconnected from the valve body at the
wiring harness connector and remain in the
CVT.

Speed Sen. Vol.

a. Remove the CVT from the vehicle, place it on a workbench and then remove
the valve body.
 Refer to the Electronic Service Manual (ESM), section TM-Transaxle &
Transmission for removal information.
HINT: The number “7” is on the head of all bolts that need to be removed for
valve body removal. Do not remove any bolt that does not have the
number “7”.
For AWD Vehicles use extreme care when moving the axle in and
out of the transfer assembly to avoid seal damage.
b. Position the CVT on the workbench with the oil pan side down.
IMPORTANT: Do not hit the manual shaft while flipping the CVT; the manual
shaft protrudes past the CVT case. Use a plastic / wooden block to
support as needed.
c. Proceed to step 14 on page 18.
4.

Remove the valve body.


Before lifting the vehicle place the transmission gear selector in Neutral.



Refer to the appropriate ESM, section TM – Transaxle & Transmission, for valve
body removal.
HINT: The number “7” is on the head of all bolts that need to be removed for
valve body removal. Do not remove any bolt that does not have the number “7”.
Never allow any chemicals or fluids other than NS-3 CVT fluid or
equivalent to enter the CVT assembly. Never allow any foreign debris, dust,
dirt, etc. to enter the CVT assembly.

CVT Chain Inspection

5.

Secure the right front tire with a suitable strap.

6.

Mark the left front tire with a suitable marking.


7.

This will assure all 360° of the chain is
inspected.

Using borescope J-51951 with mirror attachment,
visually inspect the entirety of the two sides of the
chain that come in contact with the pulleys:

Figure 9
a. First inspect the entirety (360°) of the driver side of the chain that comes in contact
with the pulley (see page 11, Figure 13 and Figure 14, and page 12 Figure 15).
b. If the inspection result is OK on all 360°, inspect all 360° of the passenger side of
the chain.
IMPORTANT:
 Reference the pictures on pages 13-15 for chain image comparison.
 Be sure to remove the protective film from the mirror before the first use.
 Clean the camera lens and mirror before each inspection. Use 90% isopropyl
alcohol, and a lens swab from the Lens Swab packet J-51963 listed in
PARTS INFORMATION.
