For 1990-2009 cars

### Removal Procedure

1. Ensure that removal of the valve body is necessary before proceeding.

| Important: The following components can be serviced without removing the valve body from the transmission:

• | The torque converter clutch (TCC) solenoid (1)

• | The pressure control solenoid (2)

• | The internal wiring harness (3)

• | The 2-3 shift solenoid (4)

• | The 1-2 shift solenoid (5)

• | The transmission fluid pressure (TFP) manual valve position switch (6)

• | The 3-2 shift solenoid (7)

• | The torque converter clutch pulse width modulation (TCC/PWM) solenoid (8)

2. Remove the fluid level indicator.
3. Remove the oil pan, and filter. Refer to Automatic Transmission Fluid and Filter Replacement .
4. Disconnect the internal wiring harness electrical connectors from the following components:

• | The TFP manual valve position switch (1)

• | The 1-2 shift solenoid (2)

• | The 2-3 shift solenoid (3)

• | The pressure control solenoid (4)

• | The TCC/PWM solenoid (5)

• | The 3-2 shift solenoid (6)

5. RWD ONLY:

5.1. | Remove the fluid indicator stop bracket bolt (2).

5.2. | Remove the fluid indicator bracket (1).

6. Remove the TCC/PWM solenoid retainer (2) with a small screwdriver. Rotate the solenoid (1) in the bore, if necessary, until the flat part of the retainer (2) is visible.
7. Remove the TCC/PWM solenoid (1) in order to access the TCC solenoid retaining bolts.
8. Remove the TCC solenoid retaining bolts.
9. Remove the TCC solenoid with O-ring seal, and wiring harness from the control valve body.
10. Reposition the harness to the side of the transmission case.
11. Remove the control valve body bolts securing the TFP manual valve position switch to the control valve body.
12. Remove the TFP manual valve position switch.
13. Inspect the TFP manual valve position switch for the following conditions:

• | Damage

• | Debris

• | Damaged or missing O-rings

• | Cracked connector

• | Loose electrical terminals

• | Poor terminal retention

• | Sediment in switch membrane

14. Remove the manual detent spring bolt.
15. Remove the manual detent spring.
16. Inspect the manual detent spring for cracks or damage.
17. Remove the remaining control valve body bolts.

Important: Keep the control valve body level when lowering it from the transmission case. This will prevent the loss of checkballs located in the control valve body passages.

18. Carefully begin to lower the control valve body down from the transmission case while simultaneously disconnecting the manual valve link from the manual valve.

### Installation Procedure

1. Install the checkballs (1-7) in the valve body.

Important: Keep the control valve body level when raising it to the transmission case. This will prevent the loss of checkballs located in the control valve body passages.

2. Install the control valve body to the transmission case while simultaneously connecting the manual valve link to the manual valve.
3. Verify that the manual valve link (3) is installed properly to the inside detent lever (1) and the manual valve (2).
4. Install one bolt (M6 X 1.0 X 47.5) hand tight in the center of the valve body to hold it in place.

Important: When installing bolts throughout this procedure, be sure to use the correct bolt size and length in the correct location as specified.

5. Do not install the transmission fluid indicator stop bracket and bolt at this time, if equipped

Install but do not tighten the control valve body bolts securing only the valve body directly.

Each numbered bolt location corresponds to a specific bolt size and length, as indicated by the following:

• | M6 X 1.0 X 65.0 (1)

• | M6 X 1.0 X 54.4 (2)

• | M6 X 1.0 X 47.5 (3)

• | M6 X 1.0 X 17.7 (4)

• | M6 X 1.0 X 35.0 (5)

6. Install the TFP manual valve position switch.
7. Install but do not tighten the control valve body bolts securing the TFP manual valve position switch to the control valve body.

Notice: Refer to Fastener Notice in the Preface section.

Notice: Do not over-tighten the bolts. Over-tightening the bolts will distort the valve bores. Begin tightening from the center of the valve body tighten the bolts in a outward direction.

8. Tighten the control valve body bolts in a spiral pattern starting from the center and working outward.

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

9. Install the manual detent spring and bolt.
10. Ensure that the manual detent spring is aligned properly with the detent lever.

Tighten
Tighten the manual detent spring bolt to 31 N·m (23 lb ft).

11. Install the TCC solenoid with a new O-ring seal to the valve body.
12. Install the TCC solenoid bolts.

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

13. Install the TCC/PWM solenoid (1) to the control valve body.
14. Install the TCC/PWM solenoid retainer (2).
15. RWD ONLY:

Install the transmission fluid indicator stop bracket (1) and bolt (2).

Tighten
Tighten the transmission fluid indicator stop bracket bolt to 11 N·m (97 lb in).

16. Snap the wiring harness in place on the valve body bolts. Ensure the harness loom tab is located under the TFP switch.
17. Connect the internal wiring harness electrical connectors to the following components:

• | The TFP manual valve position switch (1)

• | The 1-2 shift solenoid (2)

• | The 2-3 shift solenoid (3)

• | The pressure control solenoid (4)

• | The TCC/PWM solenoid (5)

• | The 3-2 shift solenoid (6)

18. Install the transmission filter and oil pan. Refer to Automatic Transmission Fluid and Filter Replacement .

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