Shift Solenoid: Service and Repair

Shift Solenoids (SS)













Removal

1. Remove the main control. For additional information, refer to Main Control Removal and Replacement.

2. Remove the 6 long bolts from the molded leadframe.





3. Carefully separate the molded leadframe from the main control assembly.

1. Molded leadframe.

2. Main control.





4. Remove the 8 solenoid bracket bolts and the solenoid bracket.





5. NOTICE: A Variable Force Solenoid (VFS) is calibrated from the factory and are not all the same. To replace a VFS, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh/erratic shifts, harsh/soft engagement or damage to the transmission can occur.

If replacing more then 1 solenoid, number the solenoids and number the main control solenoid ports to correspond to the solenoid. Pull the solenoid(s) out of the main control valve body.





Installation

1. NOTICE: A VFS is calibrated from the factory and are not all the same. To replace a VFS, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh shifts or damage to the transmission can occur.

Use the solenoid exploded view at the beginning of this procedure to identify what type of solenoid is being replaced. The solenoid can be a normally high VFS, normally low VFS or an ON/OFF solenoid.
If replacing a VFS, record the band number to get the correct part number for the solenoid.
Lubricate the solenoid O-rings with clean transmission fluid.

2. Solenoid band number





2. Position the solenoid(s) in the main control in the correct port(s) as marked during removal.





3. Position the solenoid bracket in place and install the 8 bolts.
- Tighten to 6 Nm (53 lb-in).





4. NOTE: The TR sensor pin must be aligned with the manual control valve during installation.

Position the molded leadframe on the main control.

1. Molded leadframe.

2. Main control.

3. TR sensor pin.





5. Install the 6 long bolts into the molded leadframe. Tighten the bolts in the sequence shown.
- Tighten to 6 Nm (53 lb-in).





6. Install the main control. For additional information, refer to Main Control Removal and Replacement.
