Lincoln Corsair: Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40 / Removal and Installation - Solenoid

Materials

Removal

NOTICE: Failure to match the replacement solenoid service band to the original solenoid can cause damage to the transmission or erratic engagements and shifts.

NOTE: The solenoids that are being re-used must be marked during the removal and reinstalled in the exact bore location.

NOTE: While removing and installing solenoids, never handle the plastic connector.

1. Using the scan tool Transmission Solenoid Identification Number (IDN) function, retrieve the solenoid base part number and stamping number.
   Refer to: Transmission Description (307-01A) .
   

1. Remove the main control valve body.
   Refer to: Main Control Valve Body (307-01A Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40, Removal and Installation).
   

1. Remove the solenoid body from the main control valve body.
   Refer to: Main Control Valve Body (307-01A Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40, Overhaul).
   

1. Remove the bolts and the park lock solenoid.
   

1. NOTICE: The solenoids are calibrated from the factory and are not all the same. Failure to mark the solenoids to the ports they were originally in can result in mixing the solenoids and can cause damage to the transmission or a harsh shift.

   NOTE: Note the position of the components before removal.

   1. SSA (CB12345)
      
   2. SSF (CB28)
      
   3. SSB (C46R)
      
   4. SSD (SOWC)
      
   5. SSE (C5678)

1. NOTE: If installing a new component, determine the part number.

   1. Armature/pin assembly
      
   2. Part information
      

1. NOTE: All other shift solenoids similar.

   Discard the retainer clip and remove the suspect solenoid. All other solenoids can remain in place.
   

1. 1. TCC solenoid
      
   2. LPC solenoid
      

1. NOTE: If installing a new component, determine the part number.

   2. Part information
      

1. Remove the bolt and the clamp. Remove the TCC solenoid.
   

1. Remove the bold and the clamp. Remove the LPC solenoid.
   

Installation

NOTICE: Extreme cleanliness must be exercised when handling the components.

NOTICE: Make sure that solenoids are installed to the position noted before removal to prevent the damage to the transmission.

1. Lubricate the TCC and the LPC solenoid O-rings seals with automatic transmission fluid.
