2007 Chevrolet Impala V6-3.9LSECTION Torque Converter Clutch Pulse Width Modulation Solenoid Replacement


Torque Converter Clutch Pulse Width Modulation Solenoid Replacement

Removal Procedure




1. Remove the case side cover.
2. Disconnect and reposition the electrical connectors from the following:

* If equipped internal mode switch
* 2-3 Shift solenoid valve assembly (315B)
* Automatic transaxle fluid pressure manual valve position switch assembly (395)





Important: Do NOT remove the bolt (205) that holds the oil pump together.

3. Remove the oil pump bolts (206,207).




4. Remove the oil pump (200) from the valve body (300).




5. Disconnect the torque converter clutch pulse width modulation (TCC PWM) solenoid electrical connector.
6. Remove the TCC PWM solenoid retaining clip (314F).
7. Remove the TCC PWM solenoid (334).

Installation Procedure




1. Install the TCC PWM solenoid (334).
2. Install the TCC PWM solenoid retaining clip (314F).
3. Connect the TCC PWM solenoid electrical connector.




4. Install the oil pump (200) to the valve body (300).





Notice: Refer to Fastener Notice.

5. Install the oil pump body and cover bolts (206,207).

* Tighten the bolts (207) to 12 N.m (106 lb in).
* Tighten the bolts (206) to 16 N.m (12 lb ft).




6. Reposition and connect the electrical connectors to the following:

* Automatic transaxle fluid pressure manual valve position switch assembly (395)
* 2-3 Shift solenoid valve assembly (315B)
* If equipped internal mode switch

7. Install the case side cover.

Important: It is recommended that transmission adaptive pressure (TAP) information be reset. Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

8. Reset the TAP values. Refer to Transmission Adaptive Functions.
