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 1).

Dowel pin
locations

Figure 1

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.

2. Disconnect both battery cables, negative cable first.
3. Is DTC P17F0 stored?

YES:
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.
NOTE: 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”.
CAUTION: 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.
CAUTION: 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 4 on page 18.

NO: Proceed to step 4.

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.
NOTE: 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”.
CAUTION: 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.

For additional information, see video # 546: “CVT Chain Inspection”. This video is
located under the TECH TRAINING GARAGE VIDEOS tab in Virtual Academy.

CVT Chain Inspection
1. Secure the right front tire with a suitable strap.
2. Mark the left front tire with a suitable marking.

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

3. 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 4
a. First inspect the entirety (360°) of the driver side of the chain that comes in contact
with the pulley (see page 11, Figure 8 and 9, and page 12, Figure 11).
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 page 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.
 Before inspecting, make sure the camera handle’s AA batteries are fresh and the
LCD monitor’s battery is charged.
 Insert the camera lens behind the pulley between the guide rail and the pulley where
shown in Figure 5 (also see page 10-11, Figure 6-9).
 Insert the lens approximately 8-9 inches, and then view the side of the chain that
contacts the pulley.
 Refer to Garage Video #546 if needed for Borescope inspection.
