Control Valve Body Harness Removal / Installation

CONTROL VALVE BODY HARNESS REMOVAL / INSTALLATION

Removal Note
1. Drain the transmission fluid.

Note:
^ The control assembly does not need to be removed.

2. Disconnect vehicle harness from the 16 pin transmission case electrical connector.
3. Remove the transmission oil strainer.
(1) Remove the transmission oil strainer bolt.
(2) Remove the transmission oil strainer.





4. Remove the main control valve body wire loom.
^ Carefully lift up on the wire loom guide and protector and disengage the retaining pins from the solenoid clamps.





5. Disconnect the solenoid electrical connectors.
(1) Disconnect the SS1, SS2, SS3 and the CCS/SS4 electrical connectors.
(2) Disconnect the torque converter clutch (TCC) solenoid electrical connector.
(3) Disconnect the electronic pressure control (EPC) solenoid electrical connector.





Caution:
^ The TCC solenoid and converter modulator valve may pop out of its bore. This may damage the solenoid or converter modulator valve.
Shift solenoids may pop out of their bore. This may damage the solenoids.

6. Remove the EPC and SS2 solenoids.
(1) Remove the solenoid clamp bolts.
(2) Remove the solenoid clamp.
(3) Remove the EPC and SS2 solenoids.





Caution:
^ Do not pry on the other wires or damage the connector case surface.

7. Disconnect the turbine shaft speed (TSS) sensor electrical connector from the 16 pin transmission case electrical connector.
(1) Disconnect the TSS sensor electrical connector.
(2) Remove from the TSS sensor wire locator.





Caution:
^ Do not overstretch the retaining spring.

8. Remove the 16 pin transmission case electrical connector retaining spring.





Caution:
^ Do not damage the connector or harness.

9. Remove the 16 pin transmission case electrical connector.
(1) Compress the tabs on the 16 pin transmission case electrical connector.





10. Push the 16 pin transmission case electrical connector out of transmission case.





Installation Note

Note:
^ Make sure the tab is in the lock position.
Install new O-rings on the transmission case (16 pin) electrical connector.

1. Install the 16 pin transmission case electrical connector.
(1) Lubricate the 16 pin transmission case electrical connector O-rings with petroleum jelly.





Caution:
^ Align the slot on the TSS sensor electrical connector with the slot in the 16 pin transmission case electrical connector.

2. Press the 16 pin transmission case electrical connector through the case until a click is heard.





Caution:
^ Align the slot on the TSS sensor electrical connector with the slot in the 16 pin transmission case electrical connector.

3. Install the TSS sensor wire.
(1) Install the TSS sensor wire into 16 pin transmission case electrical connector.
(2) Install the TSS sensor wire into the locator.





Caution:
^ Do not overstretch the retaining spring.

4. Install the 16 pin transmission case electrical connector retaining spring.





5. Install the EPC and SS2 solenoids.





Caution:
^ The solenoid clamp must be installed in the TCC and EPC solenoid grooves, shift solenoid pockets and the No. 204 plug.

6. Install the solenoid clamp.
(1) Position the solenoid clamp on the main control valve body.
(2) Install the solenoid clamp bolts.





7. Connect the SS1 and SS3 electrical connectors.





8. Connect the TCC, CCS/SS4, SS2, and EPC solenoid electrical connectors.





Caution:
^ Excessive pressure may break the retaining pins.

9. Install the wire harness guide and protector.
(1) Align the retaining pins to the holes in the solenoid clamps and gently press in the wire harness guide and protector.





10. Install the oil strainer and bolt.





11. Install the oil pan.
(1) Position a new oil pan gasket on the oil pan.
(2) Align and install the oil pan.





12. Loosely install the 18 oil pan bolts.

Note:
^ Use a crisscross sequence to tighten the transmission oil pan bolts.

13. Tighten the oil pan bolts.





14. Connect the vehicle harness to the 16 pin transmission case electrical connector. Make sure the lock is fully engaged.
15. Lower the vehicle.

Note:
^ When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts either soft or firm and this is a temporary condition and will eventually return to normal operating condition.

16. Connect the negative battery cable.
17. Fill the transmission to the proper fluid level and check for proper transmission operation.
