Service Procedure
TCM Reprogramming And Initialization1. Connect CONSULT III (C-III) to the vehicle to begin the reprogramming procedure.
CAUTION
2. When you get to the TCM Reprogramming screen shown in Figure 1, confirm TCM reprogramming applies as follows.
A. On your C-III screen, look at the Part Number (P/N) column (see Figure 1).
^ Write down the P/N on the Repair Order.
B. Compare the P/N you wrote down to the numbers in the Current TCM P/N column in Table A.
^ If there is a match, perform TCM reprogramming and initialization.
NOTE:
If there are two lines (two reprogramming options) on your C-III screen, use the one that does not have the message "Caution! Use ONLY with NTBXX-XXX".
Replace Control Valve Assembly
CAUTION:
Transmissions are very vulnerable to particles (dust, metal, etc.).
^ When removing the oil pan, make sure your work environment (shop, workbench, etc.), vehicle 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.
^ Wait to unpack Service Parts until just before installation.
1. Write down all radio station presets.
2. Disconnect both battery cables; negative cable first.
3. Remove the CVT dipstick. Raise the vehicle on a hoist.
4. Remove the engine undercover from below the front bumper cover (see Figure 2).
5. Remove the transmission pan drain plug and drain the CVT fluid.
6. Loosen and remove the 20 oil pan bolts to remove the oil pan.
7. Disconnect CVT harness connector F6 by turning it in the direction shown in Figure 3.
8. Remove the nut and lock nut to remove the manual plate (see Figure 4).
9. Remove the collar from the manual shaft (see Figure 5).
10. Remove the large lock ring holding the CVT connector to the transmission case (see Figure 6).
^ Push the transmission side of the harness down inside the transmission case to remove it.
^ Transmission side of CVT harness connector and lock ring shown removed from the transmission case (see Figure 7).
11. Disconnect the harness from the Primary oil pressure sensor assembly (see Figure 8).
12. Remove the bolts attaching the control valve assembly to the transmission (see Figure 9).
^ There are 11 bolts shown and numbered for convenience.
^ There are 3 different length bolts which are identified by:
S-short
M-medium
L-long
13. Carefully remove the control valve assembly.
^ Note the position of the Ratio Control Valve and attached shift link (see Figure 10).
^ Be careful not to allow the Ratio Control Valve to fall out.
14. Make sure you replace the 2 lip seals shown in Figure 11.
^ Do not reuse the old lip seals.
^ Use petroleum jelly to keep the new lip seals in place during reassembly.
Install the replacement Control Valve Assembly:
15. Carefully install the new control valve assembly and shift link with the fork end of the shift link around the pin (see Figure 12).
16. While you are doing Step 15 above, the lower end of the shift link must stick through the bottom of the step motor pin as shown in Figure 13.
17. Install finger tight the 11 control valve assembly bolts removed in Step 12.
^ Make sure the different lengths of bolts are installed in the correct holes (see Figure 9).
IMPORTANT CHECKS:
^ After you install the new control valve assembly, 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.
18. Torque the 11 control valve assembly bolts.
^ Tightening torque: 6.9-8.9 N-m (0.7-0.9 kg-m, 61-78 in-lbs).
^ Torque sequence as per Figure 9: 6-7-5-8-4-9-3-10-2-11-1.
^ Refer to Figure 9 for bolt numbering and position.
19. Reinstall the collar on the manual shaft (see Step 9, Figure 5).
20. Align the manual plate with the notch in the manual valve (see Figure 14).
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: 20.6-23.5 N-m
(2.1-2.3 kg-m, 15.1 - 17.3 ft-lbs)
21. Reconnect the harness to the primary oil pressure sensor (see Step 11, Figure 8).
22. Reinsert the CVT connector with locking ring into the case as shown in step 4, Figure 6. Make sure that the locating notch is properly engaged.
Install Oil Pan:
1. Install the oil pan and bolts.
^ Make sure oil pan and magnets are free of contamination particles.
^ Tightening Torque: 5.4 - 7.4 N-m (0.5-0.7 kg-m, 47.8 - 65.5 in-lbs).
2. Install the battery cables, negative cable last.
3. Fill and check the CVT fluid level.
4. Reprogram the radio presets.
5. Reset the clock.
6. Initialize the power windows and sunroof as applicable. Reference the ESM as needed.
7. Using C-III, make sure to erase DTCs from all Systems.
8. Test drive the vehicle and make sure it operates correctly, and:
^ The CVT Position Indicator in the combination meter displays correctly in ALL gear selector positions. See Figure 1 for indicator location.
^ 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 Control Valve Assembly replacement are not covered by this bulletin.
