If the inspection result is OK on both sides of the belt, replace the control valve
(page 73).



If the inspection result is NG, replace the CVT sub-assembly (page 18) and
control valve (page 73).

CVT Assembly Removal
Overview of Sub-assembly Repair
Steps 1-15 below are an overview of the CVT sub-assembly repair. The procedure for this
bulletin continues on the next page with step 9.

1. Apply rust penetrant as necessary to the dowel pins on the converter
housing side and sub-assembly side cover
2. Remove the CVT from the vehicle
3. Remove the Converter Housing, Oil Seals, Oil Pump Cover, Oil Pump and
Oil Filter
4. Clean the CVT case surfaces
5. Clean the Oil Passages in the CVT Case, Oil Pump Cover, and CVT Filter
Area
6. Check initial pulley movement characteristics
7. New Pump Installation
8. Replace the Side Cover – Pulleys and Belt
9. Confirm shift selector movement
10. Recheck new pulley movement characteristics matches that of the original
assembly
11. Clutch Total Endplay Adjustment – Thrust Bearing Selection
12. Clean the Converter Housing Passages
13. CVT Reassembly
14. Control Valve, Strainer, and Pan Installation
15. Install the CVT Assembly
HINT: For additional information review video # 547: “CVT Belt and Pulley
Replacement”.

Temporarily install the oil pan gasket and oil pan with four (4) oil pan bolts at the
corners of the oil pan, hand tight (Figure 24).
HINT: It is not necessary for the control valve to be installed, a new one will be
installed later in the service procedure.

Remove the CVT from the vehicle.


On AWD models, refer to the ESM: TRANSMISSION & DRIVELINE > CVT:
RE0F10D > REMOVAL AND INSTALLATION > TRANSAXLE ASSEMBLY >
AWD



On FWD models, refer to the ESM: TRANSMISSION & DRIVELINE >
TRANSAXLE & TRANSMISSION > CVT: RE0F10D > UNIT REMOVAL AND
INSTALLATION > TRANSAXLE ASSEMBLY

To avoid seal damage or deformation on AWD vehicles, use extreme care when
moving the axle in or out of the transfer case assembly. Properly support and guide
the axle.

11.

Place the CVT on a workbench with
the oil pan side down.

To prevent deformation to the oil pan,
use wood or plastic blocks to keep the
CVT steady.

12.

Remove the torque converter.

Remove the Converter Housing, Oil Seals, Oil Pump Cover, Oil Pump and Oil Filter

15.

Remove all 23 converter housing
mounting bolts (Figure 28).
HINT:


These bolts will be replaced with
new ones and will not be reused.



Use a short socket on the bolts
indicated by .
Apply rust penetrant to the dowel
pin if needed.



Separate and then remove the converter housing from the CVT case.


Use Slide Hammer J-25721-A and Slide Hammer Bolt J-50255-UPD with J-Hook
J-51923 at the cut-out areas similar to the one, as shown in Figure 29 and
Figure 30.
To avoid damage to the vehicle DO NOT use a pry-bar, chisel, etc. to separate the
converter housing from the CVT case.

Remove the following oil seals using
suitable tools:
To avoid damage to the seal bore
surfaces, use care when removing the
seals.

Remove the two (2) nuts from baffle
plate A, and then remove baffle
plate A (Figure 39).

To avoid damaging the nuts, use a
6-pt 10 mm socket.

23.

Remove the oil pump chain, driven sprocket and drive sprocket as one assembly
(Figure 40).


Spread the snap ring to remove the sprocket (Figure 41).

HINT: The drive sprocket has a specific top and bottom. Keep the sprockets and
chain together after removal.



Lift the dummy cover from the sides ONLY. Do NOT lift from the input shaft
(Figure 47). This can lift the clutch pack out.



Do NOT remove the lathe cut seals (white seals in Figure 48) from the dummy
cover. These seals will be reused.



Lathe cut seals must be in their correct positions during final assembly to
prevent drivability issues.

thrust bearing so that the lathe cut
seals are not knocked out of their
grooves.



Thrust bearing
The thrust bearing has two
different sides. As the thrust
bearing is removed, note the thrust
bearing orientation so that the new
bearing can be installed in the
same orientation.
