Hi and thanks for using 2CarPros.

There is no switch but rather a torque converter clutch solenoid. It is located on the valve body inside the transmission. Here are the directions for accessing the shift solenoids as well as the TCC solenoid. The solenoid you are referring to is indicated as TCC solenoid. The attached pictures correlate with the directions.

VALVEBODY SOLENOID REMOVAL

IMPORTANT: Only remove valve body cover. The valve body does not have to be removed from the trans-axle to gain access to the solenoids.

1. Remove valve body cover.

Picture 1

2. Remove solenoid cover-to-valve body bolts (identified by the heavy circles) and remove solenoid cover. The solenoids are identified below:
1 Pressure Control Solenoid
2) Shift Solenoid 2
3) TCC Solenoid
4) Shift Solenoid 4
5) Shift Solenoid 3

Picture 2

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

IMPORTANT: Note position of solenoid valve(s) before removing.

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

INSTALLATION
1. Lube solenoid O-rings.
2. Install solenoids with a twisting motion.

Picture 3

3. Check 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.

Picture 4

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

IMPORTANT: Clean and lubricate fasteners with Saturn Trans-axle Fluid. Wipe off excess fluid.

IMPORTANT: The dowel bolts must be placed in the holes shown to align the upper valve body to the lower valve body. The solenoids are identified below.

7. Install the solenoid cover bolts and finger tighten.
1) Pressure Control Solenoid
2) Shift Solenoid 2
3) TCC Solenoid
4) Shift Solenoid 4
5) Shift Solenoid 3

NOTICE: Over-torqueing bolts can cause valves to bind.

8. Torque solenoid cover bolts using torque sequence shown in illustration.
Torque:
Valve body Assembly Bolts: 11 Nm (8 ft. Lbs.)

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

9. Install Valve body cover.
