Service Procedure
Reprogram TCM1. Connect CONSULT III (C-III) to the vehicle to begin the reprogramming procedure.
^ If you are not familiar with the reprogramming procedure refer to the "CONSULT- III (C-III) TCM Reprogramming general procedure.
CAUTION
2. When you get to the TCM Reprogramming screen shown in Figure 1, confirm this bulletin applies as follows:
A. On your C-III screen, look at the Part Number column (see Figure 1 example).
^ If this column is blank (no part number listed), this bulletin does not apply.
^ If a part number (P/N) is listed, write it on the Repair Order and then go to Step B.
B. Compare the P/N you wrote down to the P/Ns in the Current TCM P/N column in Table A above.
^ If there is a match, this bulletin applies. Continue with reprogramming and the entire Service Procedure.
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".
^ If there is not a match, this bulletin does not apply. Refer to ASIST for further diagnostic and repair information.
3. If this bulletin applies and you have performed TCM reprogramming; when reprogramming is complete, the screen in Figure 2 displays.
4. Make sure to erase DTCs from all systems. During reprogramming, DTCs will set in several systems and must be erased.
Replace CVT Assembly
1. Write down all radio station presets.
2. Remove the old CVT assembly from the vehicle.
^ Refer to the appropriate section of the ESM as needed.
3. Remove the CVT oil warmer from the old CVT assembly, and then install it on the new CVT assembly (see Figure 3).
4. Install the new CVT assembly.
^ Refer to the appropriate section of the ESM, if needed.
5. Fill / adjust CVT fluid and coolant levels as necessary.
^ Refer to the appropriate section of the ESM, if needed.
6. Reprogram the radio presets.
7. Reset / initialize all applied systems i.e., power windows, clock, sunroof, etc.
^ Refer to the ESM as needed.
TCM Initialization Procedure
1. Set the parking brake with the selector lever in "P" (Park).
2. C-III and the Vehicle Interface (VI) should still be on and connected, and the vehicle ignition turned 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).
NOTE:
^ If the initialization (EEPROM erase) has completed, there will be a 1-2 second delay before the "P" displays in the meter.
^ If the "P" displays immediately, repeat a through f.
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.
Final Test Drive
Test drive the vehicle to make sure it operates correctly.
