SERVICE PROCEDURE
Disassemble CVT for Inspection
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.), the transmission area (sub-frame, oil pan, harness connector, etc.), and your
hands are free of contamination.

Make sure all parts are clean prior to assembling / installing. Unpack service parts
just before installation.

Only disassemble the parts which are mentioned in this bulletin.
NOTE: If metal debris is found in the oil pan during disassembly, this is OK. The CVT
will be flushed after reassembly, or replaced.

WARNING: CVT Fluid and parts may be hot.
4. Place the CVT on a workbench, use wood or plastic blocks to keep the CVT steady.
CAUTION: The primary speed sensor
may become damaged when handling
the CVT. Be careful when handling the
CVT (see Figure 1).

Reduction Gear Bearing Shim Selection Procedure
The following is a summary of how to select a shim with the correct thickness:
(1) Measure the bearing outer race bore depth of the CVT case (Mc).
(2) Measure the bearing outer race bore depth of the converter housing (Mh).
(3) Read the reduction gear assembly height from the label attached to the new
reduction gear assembly package.
(4) Select a shim with the measurements above using the NTB15-102 Shim Calculator
in CONSULT-III plus (C-III plus).
NOTE: CVT Service Tool Kit J-50255 and C-III plus are needed to perform the shim
selection procedure.

The Service Tool Kit’s contents are shown on page 2.
1. First, calibrate Digital Depth Gauge J-50272. For step 1a – 1d, refer to Figure 17.
a. Turn the depth gauge ON, set it to “mm” measurement.
b. Place the depth gauge’s Datum level flush on top of Gauge Block J-50271.
c. Carefully slide the depth gauge down until it bottoms out on the gauge block.
d. With the depth gauge bottomed out, press the “ZERO” switch.
 The depth gauge’s display should now read 0.00 mm.

2. Thoroughly clean the mating surfaces of the CVT case.
CAUTION: Do NOT use sanding discs or similar abrasive tools. Use brake spray or
equivalent solvent and lint-free towels only.

Make sure the brake spray or solvents used are compatible with local regulations.
For step 3-7, refer to Figure 18, 19, and 20.
3. Position the gauge block over the outer race bore in the CVT case.
4. Position the depth gauge through the middle of the gauge block.

Make sure the depth gauge’s Datum level is flush on top of the gauge block.
5. Carefully slide the depth gauge down until it bottoms out where the shim and race
bottoms out.
6. Write down the value shown in the depth gauge’s display.
7. Perform step 5 and 6 on the opposite side of the race bore.

8. Subtract 20 mm from each measurement.
EXAMPLE: 70.8 mm and 70.0 mm are the measured values. Subtracting 20 mm from
each value equals 50.8 mm and 50.0 mm, respectively.
NOTE:

20 mm is the thickness of the gauge block.

All measurements are made in millimeters.
9. Add the two measurements, and then divide by two.

Write down the calculated value as “Mc”.
EXAMPLE: 50.8 mm plus 50.0 mm equals 100.8 mm. 100.8 mm divided by
2 equals 50.4 mm Mc.
10. Perform step 2-9 on the converter housing’s outer race bore (see Figure 21).

Write down the calculated value as “Mh”.

assembly procedure.
Always restock the shim kit. This will
assure these shims are immediately
available for other future repairs.

Install CVT Assembly
NOTE: When installing a replacement (new) CVT assembly, follow the IMPORTANT
statement below.
IMPORTANT: Record a video (15 seconds maximum) of the Vehicle Identification Number
(VIN) on the F.M.V.S.S. certification label (VIN label) and either no or dissimilar damage to
the reduction gear bearings (page 8, step 2a) or the outer bearing race that can be moved
by hand (page 8, step 3b). Attach the video to the CVT Pre-Authorization Form.

Include showing no or dissimilar damage to the reduction gear bearings or the
movement of the race by hand (whichever applies) in the video.

The VIN label is located on the bottom of the driver side “B” pillar just inside the
driver door.
1. Install the CVT assembly in the vehicle.

Refer to the Electronic Service Manual (ESM), section TM-Transaxle &
Transmission, for CVT installation.
2. Flush the CVT cooler.
IMPORTANT: A CVT Cooler flush is required after a valve body or CVT assembly
replacement. Refer to bulletin NTB15-013 to perform CVT Cooler flush.
3. Connect both battery cables, negative cable last.
4. Reset / initialize all applied systems i.e., radio, power windows, clock, sunroof, etc.

Refer to the ESM as needed.
5. IMPORTANT: Install Write IP Characteristics to the TCM.

Refer to TM – Transaxle & Transmission / RE0F10D / BASIC INSPECTION, and
perform ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY.
6. For repaired CVTs only: perform Flush CVT Assembly on the next page.

Check for fluid leakage.

For replacement CVTs only: Do not perform a CVT flush. Go to step 7.
7. Verify the CVT operates normally and no abnormal noises are heard during a test drive.

Vehicle repair is now complete.

NTB15-102
Flush CVT Assembly, Verify Repairs
CAUTION: DO NOT USE any aftermarket transmission flushing equipment. For
CVT flushing, use ONLY the procedure below.
1. Top off the fluid level with up to four (4) quarts Nissan NS-3 CVT fluid or equivalent. See
PARTS INFORMATION, footnote (3) and (7).

Add as necessary.
2. With the vehicle still lifted on the hoist (wheels off the ground), run the engine in Drive
for five (5) minutes at idle speed.
3. During step 2, verify no abnormal noise is coming from the CVT.
IMPORTANT: In the next step, the wheels must be braked gradually to a stop to allow
proper CVT “downshift” ratio change. If this step is not performed properly, the CVT may
start in an incorrect ratio.
4. After five (5) minutes, gradually brake the wheels to a stop, put in Park, turn the engine
OFF, and then drain and properly discard the CVT fluid.
WARNING: CVT fluid will be HOT.
5. Reinstall the drain plug.
6. Repeat step 1 - 5.
7. After performing step 6, fill / top off with CVT fluid for the last time.

Refer to the ESM, section TM – Transaxle & Transmission / RE0F10D,
for CVT fluid filling.

Drain plug torque: 34.3 N•m (3.5 kg-m, 25.3 ft lb)

Fluid filler plug torque: 10.0 N•m (1.0 kg-m, 89 in lb)
