SERVICE PROCEDURE
Remove Control Valve Assembly
PRECAUTIONS WHEN REPLACING CONTROL VALVE ASSEMBLY
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 CVI 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 CVI fluid.
WARNING:
CVI Fluid will be hot.
7. Remove the oil pan bolts to remove the oil pan.
8. Disconnect the gray CVI harness connector by turning it in the direction as shown in Figure 1.
9. Remove the large lock ring holding the black CVI connector to the transmission case (see Figure 2).
Push the black CVI connector down inside the transmission case to remove it.
10. Remove the manual plate as shown in Figure 3.
CAUTION:
Hold the manual shaft with a 6 mm open end wrench while loosening the nut.
^ Remove the manual valve.
11. Remove the collar from the manual shaft (see Figure 4).
12. Remove the four (4) 5 mm Allen bolts to remove the CVI fluid filter assembly (filter assembly) as shown in Figure 5.
^ Be careful not to let the filter element fall out.
13. Remove the twelve (12) bolts attaching the valve body to the transmission (see Figure 6).
^ These bolts are marked by color in Figure 6.
^ There are three (3) different length bolts which are identified by:
14. Carefully remove the valve body.
^ Be careful not to allow the ratio control valve or manual valve to fall out (see Figure 3 and Figure 7).
Install Replacement Control Valve Assembly:
15. Replace the two (2) lip seals with new ones (see Figure 8).
^ Do not reuse the old lip seals.
^ Use petroleum jelly or equivalent to keep the new lip seals in place during reassembly.
16. Carefully install the new valve body as follows:
a. Remove the manual valve from the valve body before installation.
b. Lift the valve body up into the transmission with the manual shaft sliding through its hole, AND fitting the upper fork of the shift link around the pin at the same time (see Figure 9).
> Make sure the lower fork of the shift link is fitting around the step motor pin (see Figure 10).
c. Continue to lift the valve body into the transmission case until it properly seats onto its two (2) alignment dowels.
d. Install a couple bolts at opposite ends of each other finger tight, and then install finger tight the remaining bolts.
IMPORTANT CHECKS:
^ Make sure the different lengths of bolts are installed in the correct holes (see Figure 6 on Page 7).
^ After you have the new valve body in place, make sure the upper and lower forks of the shift link are positioned around their matching pins (see Figure 9 and 10).
17. Install the filter assembly with its Allen bolts finger tight.
18. Torque the valve body bolts.
^ For location of valve body bolts needing to be torqued, refer to Figure 6.
^ Torque sequence as per Figure 6: 1L, 2L, 3L, 4L, 5L, 6M, 7M, 8M, 9S, 10M, 11S, and then 12L.
19.
20. Reinstall the collar on the manual shaft (see Figure 11).
21. Install the manual valve (see Figure 12).
22. Install the manual plate while aligning it with the notch in the manual valve, and then install the lock washer and nut (see Figure 12).
CAUTION:
Hold the manual shaft with a 6 mm open end wrench while the nut is being torqued.
* Do not confuse in-lbs with ft lbs.
23. Install the black CVI connector in its transmission case mounting hole.
^ Secure it by installing its large lock ring.
^ Secure the gray CVI connector to the black CVI connector.
24. Install the oil pan with a new gasket.
^ Make sure the oil pan and magnets are clean.
25. Install the undercover.
26. Connect both battery cables, negative cable last.
27. Check the fluid level.
^ Add as necessary.
^ Inspect for fluid leaks.
28. Perform 1CM initialization.
^ Refer to TCM Initialization Procedure.
29 Reset / initialize all applied systems i.e., radio, power windows, clock, sunroof, etc.
^ Refer to the ESM as needed.
30. Using C-III, make sure to erase DTCs from all Systems.
31. Test drive the vehicle and make sure it operates correctly, and
^ The MIL is OFF, and there are no DTCs stored in ENGINE and / or TRANSMISSION.
^ If the MIL comes ON; diagnose, perform repairs, and erase DTCs.
^ Diagnosis and repairs beyond valve body replacement are not covered by this bulletin.
* Do not confuse in-lbs with ft lbs.
TCM Initialization Procedure
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.
