Transmissions are vulnerable to particles (dust, metal, lint, etc.)
^
When replacing a valve body, make sure your work environment (shop, workbench, etc.), the transmission area (sub-frame, oil pan, harness connector, etc.), and your hands are free of contamination.
^
Make sure all parts are clean prior to installing on the vehicle. Unpack Service Parts just before installation.
NOTE:
The transmission does not need to be removed for this procedure.
1. Write down all radio station presets.
2. Set the vehicle on a hoist, but do not raise it.
3. Disconnect both battery cables, negative cable first.
4. Remove the CVT dipstick, and then raise the vehicle on the hoist.
5. Remove the undercover from underneath the front bumper.
6. Remove the transmission pan drain plug and drain the CVT fluid.
WARNING:
CVT Fluid will be hot.
7. Remove the oil pan bolts to remove the oil pan.
8. Disconnect CVT harness connector F6 by turning it in the direction shown in Figure 1.
9. Remove the nut and lock nut to remove the manual plate (see Figure 2).
10. Remove the collar from the manual shaft (see Figure 3).
11. Remove the large lock ring holding the black CVT connector to the transmission case (see Figure 4).
^
Push the black CVT connector down inside the transmission case to remove it.
^
Black CVT harness connector and lock ring shown removed from the transmission case (see Figure 5).
12. Disconnect the harness from the Primary oil pressure sensor assembly (see Figure 6).
13. Remove the bolts attaching the valve body to the transmission (see Figure 7).
^
There are eleven (11) bolts shown and numbered for convenience.
^
There are three (3) different length bolts which are identified by:
^
S-short
^
M-medium
^
L-long
14. Carefully remove the valve body.
^
Note the position of the Ratio Control Valve and attached shift link (see Figure 8).
^
Be careful not to allow the Ratio Control Valve to fall out.
15. Make sure you replace the two (2) lip seals shown in Figure 9.
^
Do not reuse the old lip seals.
^
Use petroleum jelly or equivalent to keep the new lip seals in place during reassembly.
Install the replacement Control Valve Assembly:
16. Carefully install the new valve body and shift link with the fork end of the shift link around the pin (see Figure 10).
17. While you are doing Step 16 above, the lower end of the shift link must stick through the bottom of the step motor pin as shown in Figure 11.
18. Install finger tight the eleven (11) valve body bolts removed in Step 13.
^
Make sure the different lengths of bolts are installed in the correct holes (see Figure 7).
IMPORTANT CHECKS:
>
After you install the new valve body, make sure the upper end (fork end) of the shift link is positioned around the pin. Space is very limited in the work area.
>
Install the CVT dip stick and make sure there is adequate clearance between the dipstick and the harness.
19. Torque the eleven (11) valve body bolts.
^
Tightening torque.
^
Torque sequence as per Figure 7: 6-7-5-8-4-9-3-10-2-11-1.
^
Refer to Figure 7 for bolt numbering and position.
20. Reinstall the collar on the manual shaft (see Step 10, Figure 3).
21. Align the manual plate with the notch in the manual valve (see Figure 12).
NOTE:
First, tighten the nut, and then tighten the lock nut with the specified tightening torque.
^
Use a Torque wrench to tighten both the 14 mm and 19 mm nuts; same torque specification for both:
^
TORQUE
22. Reconnect the harness to the primary oil pressure sensor (see Step 12, Figure 6).
^
*Do not confuse in-lbs with ft lbs.
23. Install the black CVT connector in its transmission case mounting hole.
^
Secure it by installing its large lock ring.
^
Secure the gray F6 CVT connector to the black CVT connector.
24. Install the oil pan with a new gasket and new bolts.
^
Make sure the oil pan and magnets are clean.
^
Bolts tightening torque
25. Install the undercover.
26. Connect both battery cables, negative cable last.
1. Set the parking brake with the selector lever in "P" (Park).
2. Connect C-III and the Vehicle Interface (VI) to the vehicle and turn the ignition ON (engine OFF - not running).
3. Navigate C-III screens to Transmission, then Special Functions.
4. Select the TCM part number (P/N) and Calibration Data, and then print and save a copy.
5. Perform the initialization (EEPROM erase) procedure as follows:
a. Select Transmission Self Diagnostic Results.
b. Shift the selector lever to "R" (Reverse).
c. Press and hold the brake pedal.
d. Press and hold the accelerator pedal down about one-third, but no more than halfway. The purpose of this step is to get both the wide open throttle and closed throttle position signals to read "OFF" at the same time.
e. Press Erase.
f. Shift the selector lever to "P" (Park).
g. Turn the ignition OFF.
h. Wait 5 seconds.
i. Turn the ignition ON.
6. Select and print the TCM P/N and Calibration Data again.
7. Compare the values between the first and second Calibration Data prints.
^
The procedure is complete if the values are different.
