Torque Converter Clutch Pulse Width Modulation Solenoid, Torque Converter Clutch Solenoid, and Wiring Harness for Chevrolet Camaro 2000

Tools Required

J 28458 Power Piston Seal Protector and Diaphragm Retainer Installer

1. Remove the catalytic converter. Refer to Catalytic Converter Replacement or Oxidation Catalytic Converter Replacement in Engine Exhaust.
2. Remove the transmission oil pan and the filter. Refer to Automatic Transmission Fluid and Filter Replacement .



3. Disconnect the transmission harness 20-way connector from the transmission internal harness pass-through connector.

Depress both tabs on the connector and pull straight up; do not pry the connector.

4. Remove the 1-2 accumulator. Refer to Accumulator Assembly, Spacer Plate, and Gaskets .



5. Disconnect the internal wiring harness electrical connectors from the following components:

•	Transmission fluid pressure switch (1)

•	1-2 shift control solenoid (2)

•	2-3 shift control solenoid (3)

•	Pressure control solenoid (4)

•	TCC PWM solenoid (5)

•	3-2 control solenoid (6)




6. Remove the TCC PWM solenoid retainer.
7. Remove the TCC PWM solenoid in order to access one of the TCC solenoid retaining bolts.



8. Remove the pressure control solenoid retainer.
9. Remove the pressure control solenoid.



10. Remove the TCC solenoid retaining bolts and the valve body bolts which retain the internal wiring harness.



11. Using J 28458 , release the pass-through electrical connector from the transmission case.

11.1.

Use the small end of the J 28458 over the top of the connector.

11.2.

Twist in order to release the four tabs retaining the connector.

11.3.

Pull the harness connector down through the transmission case.

12. Remove the TCC solenoid (with O-ring seal) and wiring harness assembly from the transmission case.



13. Inspect the TCC solenoid and wiring harness assembly for the following defects:

•

Damage

•	Cracked connectors

•	Exposed wires

•	Loose pins

1. Install the wiring harness and TCC solenoid assembly with a new O-ring seal to the valve body.
2. Install the pass-through electrical connector to the transmission case.

Notice: Refer to Fastener Notice in the Preface section.




3. Install the valve body bolts which retain the internal wiring harness and install the TCC solenoid retaining bolts.

Tighten

•	Tighten the control valve body retaining bolts to 11 N·m (97 lb in).

•	Tighten the TCC solenoid retaining bolts to 11 N·m (97 lb in).




4. Install the pressure control solenoid.

Ensure that the electrical tabs are facing outboard.

5. Install the pressure control solenoid retainer and retaining bolt.

Tighten
Tighten the pressure control solenoid retaining bolt to 11 N·m (97 lb in).




6. Install the TCC PWM solenoid to the control valve body.
7. Install the TCC PWM solenoid retainer.



8. Connect the internal wiring harness electrical connectors to the following components:

•	Transmission fluid pressure switch (1)

•	1-2 shift control solenoid (2)

•	2-3 shift control solenoid (3)

•	Pressure control solenoid (4)

•	TCC PWM solenoid (5)

•	3-2 control solenoid (6)

9. Install the 1-2 accumulator. Refer to Accumulator Assembly, Spacer Plate, and Gaskets .



10. Connect the transmission harness 20-way connector to the transmission pass-through connector.

Align the arrows on each half of the connector and insert straight down.

11. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement .
12. Install the catalytic converter. Refer to Catalytic Converter Replacement or Oxidation Catalytic Converter Replacement in Engine Exhaust.

Important: It is recommended that the 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 the TAP values. Transmission performance may be affected as new TAP values are learned,
13. Reset the TAP values. Refer to Adapt Function .
