SERVICE PROCEDURE

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:


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.



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.



Store removed parts separately to prevent mix-up. (i.e. small cups)



Do not use cotton gloves or woven cloths. Latex or rubber gloves are recommended.
 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.
 Brake cleaner is acceptable to remove remaining CVT fluid and residual
sealer.
 Unpack service parts just before installation.



Use only specified sealant material.

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

2. Place the vehicle on a lift.
3. Before lifting the vehicle, Place the transmission gear selector in Neutral.
4. Disconnect both battery cables, negative cable first.
5. Raise the vehicle, and then drain the CVT fluid by removing the drain plug.


Remove engine under cover if needed.

CAUTION: 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 drain plug gasket from the drain plug.
a. Discard the removed drain plug gasket (non-reusable).
b. Replace drain plug gasket with a new one listed in the Part Information.

8. Remove the oil pan mounting bolts, and
then remove the oil pan and oil pan
gasket.


Do not discard bolts. These will be
reused during assembly.

9. Inspect inside the CVT pan for any evidence of broken parts.


Is there any evidence of broken parts or excessive debris?
EXAMPLE:
 Figure 3B is NG - Broken parts would include pieces of bearing cages,
bearings, clutch material, belt elements, etc.
 Figure 4B is OK – Magnets with fine debris or sludge in any amount.
o YES: Replace the CVT assembly as follows:
a. Document the debris found with video (see page 108 for details).
b. Re-install the CVT oil pan gasket and oil pan.
c. Call the PCC for CVT replacement authorization (see page 108 for contact
information).
d. Remove the CVT from the vehicle and then proceed to page 94.
NOTE: Refer to the Electronic Service Manual (ESM), section
TN – Transaxle & Transmission for CVT removal.
o NO: Proceed to next step to continue the repair.
