J 28458
Seal Protector Retainer Installer
Removal Procedure
- Remove the transmission oil pan and the filter. Refer to
Automatic Transmission Fluid and Filter Replacement
.
- 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.
Important: Removal of the valve body is not necessary for the following procedure.
- Remove the 1-2 accumulator assembly. Do not remove the spacer plate. Refer to
Accumulator Assembly, Spacer Plate, and Gaskets
.
- 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) |
• | 3-2 control solenoid (6) |
- Remove the TCC PWM solenoid retainer with a small screwdriver. Rotate the solenoid in the bore, if necessary, until the flat part
of the retainer is visible.
- Remove the TCC PWM solenoid in order to access one of the TCC solenoid retaining bolts.
- Remove the pressure control solenoid retainer.
- Remove the pressure control solenoid.
- Remove the TCC solenoid retaining bolts.
- Using the
J 28458
, release the pass-through electrical
connector from the transmission case.
10.1. | Use the small end of the
J 28458
over the top of the connector. |
10.2. | Twist in order to release the four tabs retaining the connector. |
10.3. | Pull the harness connector down through the transmission case. |
- Remove the TCC solenoid with O-ring seal, and wiring harness assembly from the transmission case.
- Inspect the TCC solenoid and wiring harness assembly for the following defects:
Installation Procedure
- Install the wiring harness and TCC solenoid assembly with a new O-ring seal to the transmission.
- Install the pass-through electrical connector to the transmission case.
Notice: Refer to Fastener Notice in the Preface section.
- Install the TCC solenoid retaining bolts.
Tighten
Tighten the TCC solenoid retaining bolts to 11 N·m (97 lb in).
- Install the pressure control solenoid.
Ensure that the electrical connection is facing downward.
- Install the pressure control solenoid retainer and retaining bolt.
Tighten
Tighten the pressure control solenoid retaining bolt to 11 N·m (97 lb in).
- Install the TCC PWM solenoid to the control valve body.
- Install the TCC PWM solenoid retainer.
- 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) |
• | 3-2 control solenoid (6) |
- Install the 1-2 accumulator. Refer to
Accumulator Assembly, Spacer Plate, and Gaskets
.
- 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.
- 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.
- Reset the TAP values. Refer to
Transmission Adaptive Functions
.
