Removal Procedure

Important

Only remove the valvebody cover. The valvebody DOES NOT have to be removed from the transaxle to gain access to the solenoids.





1. Remove the valvebody cover. Refer to Control Valve Body Assembly Removal .
2. Remove the solenoid cover-to-valvebody bolts, identified by the heavy circles, and remove solenoid cover. The solenoids are identified below:
• The pressure control solenoid
• The shift solenoid 2
• The TCC solenoid
• The shift solenoid 4
• The shift solenoid 3




3. Lift the solenoid connector plate off the solenoid pins using care not to damage the connector plate.

Important

Note the position of the solenoid valves before removing.

4. Remove the solenoid by twisting as the solenoid is removed.

Installation Procedure

1. Lube the solenoid O-rings.
2. Install the solenoids with a twisting motion.
3. Check the connector plate terminals with a #43 (2.25 mm) drill bit. There should be a slight drag on the shank. If there is no drag replace the connector plate.
4. Align the solenoid pins to the connector plate.




5. Install the connector plate.
6. Install the solenoid cover.





Important

Clean and lubricate the fasteners with Saturn Transaxle Fluid. Wipe off excess fluid.

Important

The dowel bolts must be placed in the holes shown to align the upper valvebody to the lower valvebody. The solenoids are identified below.

7. Install the solenoid cover bolts and finger tighten.
• The pressure control solenoid
• The shift solenoid 2
• The TCC solenoid
• The shift Solenoid 4
• The shift Solenoid 3

Notice

Refer to Fastener Notice in Cautions and Notices.






Notice

Over-torqueing bolts can cause valves to bind.

8. Torque the solenoid cover bolts using the torque sequence shown in illustration.
Tighten

Tighten the valvebody assembly bolts to 11 N·m (8 lb ft)

Important

Using the Saturn Service Stall (SSS) system, reset the adapters before driving the vehicle if the pressure control solenoid was replaced.

9. Install the valvebody cover. Refer to Control Valve Body Assembly Removal .
