In-Vehicle Repair: Solenoids: Installation

2005 Ford Taurus SEL, 4D SedanSECTION Installation
WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the solenoid(s) for damage.

  2. If a new solenoid is not being installed, install the solenoid(s) into the bore from which it was removed.
  3. If installing a new Variable Force Solenoid (VFS), determine the base part number of the solenoid(s). The Torque Converter Clutch (TCC) solenoid, Shift Solenoid A (SSA) and Shift Solenoid C (SSC) are all normally low pressure solenoids. The Line Pressure Control (LPC) solenoid, Shift Solenoid B (SSB) and Shift Solenoid D (SSD) are all normally high pressure solenoids. Shift Solenoid E (SSE) is not a VFS  , it is an ON/OFF solenoid.

    ITEM DESCRIPTION

    Item Part Number Description
    1 7G136 SSA  (normally low)
    2 7G383 SSB  (normally high)
    3 7G136 SSC  (normally low)
    4 7G383 SSD  (normally high)
    5 7G484 SSE  (normally closed [OFF])
    6 7G136 TCC  solenoid (normally low)
    7 7G383 LPC  solenoid (normally high)
  4. Determine the part number suffix by checking the solenoid service band number etched on the side of the solenoid. The band number is the third digit on the side of the solenoid and will be a 1, 2, 3, 4 or 5. Use the following table to determine the part number suffix and match the new solenoid base part number and suffix with the old solenoid.

  6. Position the leadframe on the Leadframe Guide Pins and carefully install the leadframe by pushing straight down into the solenoids.
  7. Remove the Leadframe Guide Pins.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
