Installation

Solenoids A, B, C, and F

1. NOTICE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, match the band number with the original solenoid or harsh shifts or damage to the transmission can occur.

   If new solenoids are needed, identify the solenoid band number.
   

1. 
   Install the solenoid(s) in the main control valve body in the correct port(s) as marked during removal.
   
   1. SSA (7J136)
      
   2. SSF (7J136)
      
   3. SSC (7J136)
      
   4. SSB (7J136)
      

1. Connect the electrical connectors and slide the plastic lock to the locked position.
   

1. 
   Install the new shift solenoid retainer(s) with the flat side towards the solenoids.
   
   1. Retainer flat side
      

1. Install and the shift solenoid retaining plate and the bolts.
   Torque: 106 lb.in (12 Nm)

1. Install the main control valve body.
   Refer to: Main Control Valve Body (307-01 Automatic Transmission - 10-Speed Automatic Transmission – 10R80, Removal and Installation).

   1. SSE (7J136)
      
   2. SSD (7J136)
      

1. 1. Connect the electrical connectors and slide the plastic lock to the locked position.
      
   2. Rotate the solenoid(s) in a counter-clockwise direction.
      
   3. Slide the solenoid(s) into the main control valve body bore.
      

1. 
   Install new shift solenoid retainer(s) with the flat side towards the solenoids.
   
   1. Retainer flat side
      

1. Install and the shift solenoid retaining plate and the bolts.

LPC (line pressure control) and TCC (torque converter clutch) Solenoids

1. NOTICE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, 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.

   If new solenoids are needed, identify which type (normally high/normally low) of solenoid it is and the solenoid band number.
   

1. 1. Inspect the solenoid screens for debris that may restrict fluid flow.
      
   2. Lubricate the solenoid O-ring seals.
