Control Valve (Valve Body) Strainer and Pan Installation
IMPORTANT: This section may contain different style parts than what were originally installed in the CVT. Pay
careful attention, REASSEMBLY MAY NOT BE IDENTICAL TO DISASSEMBLY.
Confirm that the QR label, control valve and CD part numbers all match before installing the control
valve.
CAUTION: Handle the valve body carefully.
1. Discard the oil strainer bracket (Figure 25).
2. Install a new lip seal. Do NOT reuse the old lip seal (Figure 26).
NOTE: Apply a small amount of petroleum jelly to the lip seal to keep it in place on the CVT.

4. Replace the metal bracket of the temperature sensor as follows:
NOTE: The new bracket will be oriented the same way the old bracket was.
a. Cut the plastic zip tie with an appropriate tool to remove the temperature sensor bracket from the

terminal harness assembly. (Figure 28).

CAUTION: Cut the plastic zip tie over the metal bracket to avoid damage to the temperature sensor.
b. Discard the removed bracket and plastic zip tie.
c. Use the plastic zip tie from Parts Information to attach the new temperature sensor bracket to the

temperature sensor of the terminal connector harness.
IMPORTANT: Locate the plastic zip tie at the center notch of three notches on the temperature
sensor.
d. Cut off plastic zip tie excess.

14. Fill the CVT assembly with NS-3 CVT fluid or equivalent.


Refer to the ESM, section TM – Transaxle & Transmission for CVT fluid filling.

15. IMPORTANT: Install Write IP Characteristics to the TCM; see ITB13-055.


Refer to TM – Transaxle & Transmission / BASIC INSPECTION, and perform ADDITIONAL
SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY.
 Check for fluid leakage.
 Attach the QR label with the new calibration data onto the transmission range switch (inhibitor
switch).
o See Figure 34 and 35 below.
o A QR Label and CD-R are included with the replacement valve body.

CVT Assembly Replacement Approval Procedures


If P17F0 is stored for CVT replacement:
a. Complete the Powertrain Call Center (PCC) CVT Preauthorization Form in ASIST.
b. Attach the C-III plus screen printouts showing the VIN and DTC to the Preauthorization Form.
c. Call the PCC for authorization at 800-973-9992 (opt 2).



If P17F1 is stored and CVT chain inspection indicates CVT assembly replacement is required:
a. Complete the PCC CVT Preauthorization Form in ASIST.
b. Attach the C-III plus screen printouts showing the VIN and DTC to the Preauthorization Form.
c. Attach the required video (15 seconds or less) to the CVT Preauthorization Form.


Failure to submit a continuous video showing evidence of chain slip and the VIN will cause
immediate denial of request for CVT unit replacement.

d. Call the PCC for authorization at 800-973-9992 (opt 2).
IMPORTANT: Make sure the video has a clear image of the VIN on the F.M.V.S.S. certification label
(VIN label).
