Installation Procedure
- Note the part unique number (PUN) before installing the valve solenoid body. Control Valve Solenoid Body Identification Information
Automatic Transmission Fluid Pump Seal (1) - Install NEW
- CAUTION:
The Park Pawl Actuator Lever must be in the park position, fully forward position, and aligned with the slot in the piston servo prior to lowering the Control Valve Assembly into place. Contact between the switch housing or magnet carrier and the end of the Park Pawl Actuator Lever during installation can damage these components and lead to failure. This damage may not be immediately apparent and may occur during subsequent vehicle operation.
NOTE:Ensure the automatic transmission fluid pump seal is in the control valve body.
NOTE:The piston servo (2) opening must be positioned correctly as shown. Use appropriate tool to position opening if necessary.
Place the park pawl actuator (1) in the park position.
- Carefully place the control valve body assembly (3) in the transmission ensuring park pawl actuator lever (1) aligns inside the piston servo opening (2).
