SERVICE PROCEDURE
IMPORTANT: Repairs performed for this bulletin require CONSULT-III plus (C-III plus)
Diagnostic result reporting function-Setting be turned ON and Diagnosis (All
Systems) be performed. If not done, it may result in a repair being non-warrantable.
Precautions when Disassembling a CVT Assembly
IMPORTANT:
Transmissions are vulnerable to particle contamination (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
any contamination.
It is essential that any foreign contamination be kept out of the CVT internals. Disassembly
and re-assembly shall be carried out under the following conditions:
To prevent possible drivability concerns, cover all air breather and drive shaft holes to
prevent water intrusion.









Wash and clean the exterior of the CVT assembly prior to disassembling.
Work in a covered indoor room to prevent contamination of the CVT.
Work on clean stainless drain table.
Avoid debris from dropping into the converter housing, side cover or CVT case.
Remove any sealant remaining on bolts or mating surfaces of the converter housing,
side cover and/or the CVT case using a scraper, and then clean with lint-free paper
cloths.
Do not use cotton gloves or woven cloths. Latex or rubber gloves are recommended.
o Only lint-free paper cloths.
Apply rust penetrant to locator / dowel pins on torque converter housing and side
cover of CVT and allow to soak as needed.
Only disassemble those parts which are mentioned in this bulletin.
Make sure all parts are clean prior to assembling / installing.



o Brake cleaner is acceptable to remove remaining CVT fluid and residual sealer.
o Unpack service parts just before installation.
Use only specified sealant material.




Parts cups


Store the related parts that have
been removed separately to prevent
being mixed up; small cups can be
used.

Non-warrantable damage to the CVT may occur if the steps in this procedure are not
followed in order.

Inspection for Abnormal Noise
HINT: If DTCs are stored, abnormal noise may be present.
Listen for any abnormal CVT noises under the following conditions:
Set the parking brake, and start the engine.


If an abnormal CVT noise stops once the CVT is shifted into Drive (D) or Reverse
(R), this bulletin does not apply.
o Refer to ASIST for further diagnostic information.



If an abnormal CVT noise occurs while the CVT is in Drive (D) or Reverse (R),
proceed to Control Valve (Valve Body) Removal on the next page.

5.

Raise the vehicle, and then drain the CVT fluid by removing the drain plug.


6

Remove the engine under cover, if needed.

To avoid the risk of minor personal injury, use caution when looking into the drain hole
as there is the risk of fluid entering the eye.
6.

Disconnect the engine room harness from the CVT.

7.

Remove the fifteen (15) oil pan bolts,
and then remove the oil pan and oil
pan gasket.


Step 8 continued
Is there any evidence of broken parts or excessive debris?


YES: Replace the CVT assembly as follows:
a. Document the debris found with a video (see page 153 for details).
b. Re-install the CVT oil pan gasket and oil pan.
c. Call the PCC for CVT replacement authorization (see page 153 for contact
information).
d. Refer to the ESM: TRANSMISSION & DRIVELINE > TRANSAXLE &
TRANSMISSION > CVT: RE0F11B > UNIT REMOVAL AND INSTALLATION
> TRANSMISSION ASSEMBLY



NO:
o If DTC P17F0 is not stored, proceed to next step to continue the repair.
o If DTC P17F0 is stored, proceed to Remove CVT from the Vehicle and
Disassemble External Parts on page 31.

9.

Remove the magnets from the oil pan.
NOTE: The CVT pan may come with two (2) or three (3) magnets.

CVT Belt Visual Inspection
18.

Secure the passenger side (RH) front wheel with a suitable strap.
a. Connect the first hook of the strap to the coil spring as shown in Figure 25.
b. Route the strap around the center of the tire and attach the second hook through
the eyelet of the first hook that is attached to the coil spring.
c. Tighten the strap sufficiently to keep the passenger side (RH) front tire from
rotating but do not overtighten.
o This will assist in making the belt turn during the borescope belt inspection
step.

Mark the driver side (LH) front wheel with a suitable marking.


This will ensure all 360° of the belt are inspected.

20.

Inspect the entirety of the two sides of the belt that come in contact with the pulleys
(Figure 26).
IMPORTANT:


Reference Figure 39 through Figure 47 on pages 25 - 28 for comparison.



Use borescope J-51951 with mirror attachment.



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 Lens Swab packet J-51963 listed in PARTS
INFORMATION on pages 145 and 146.



Before inspecting, make sure the batteries in the camera handle and LCD monitor
are charged.

a. Install the Clutch Engagement Tool (J-52273) to the CVT case with two bolts,
finger tight, where shown in Figure 27 and Figure 28 on page 19.
o Bolt torque not to exceed: 2.26 N•m (0.23 kg-m, 20 in-lb.)

o Use care when tightening the bolts as damage to the bolts/CVT could occur.
o Make sure an O-ring is installed to the Clutch Engagement Tool (J-52273)
before installation as this could lead to improper/incomplete testing.

18/153

NTB22-021

HINT: The O-ring for the Clutch Engagement Tool comes with the attachment. To order
additional O-rings, refer to PARTS INFORMATION on page 145.

b. Connect the hand pump from EVAP
Pressure Test Kit (J-42909) to the
Clutch Engagement Tool (J-52273)
and pump to 30 PSI (Figure 29).
IMPORTANT: Proper pressure has
been achieved when the CVT belt
moves while the driver side (LH) front
wheel is rotated and the CVT is in
NEUTRAL with the passenger side
(RH) front wheel secured.

o Do NOT over-pressurize the system as internal damage to the CVT could result.
o The hand pump should be removed from the Clutch Engagement Tool
(J-52273) quick connect once the clutch has been engaged and the belt is
observed moving with tire rotation. Pressure will be retained.
