Solenoid Pack Assembly Ford 5R55W 5R55S
Fits 2004-up

Rebuilders now have a no-hassle option of replacing worn or contaminated 5R55W and 5R55S solenoid blocks with Sonnax 56954L remanufactured solenoid blocks. The improved design of these blocks features a new, integrated, printed circuit board in place of the OE circuit assembly that eliminates fatigue failures common to the ribbon cable inside the OE circuit assembly. In addition, the integrated circuit boards soldered connections provide a more secure interconnection than the OE barbed, press-fit connection for greater durability. All remanufactured solenoids are 100% tested.

  • New integrated circuit board
  • Improved design over OE
  • No-hassle direct replacement
  • Remanufactured solenoids are 100% tested
  • New Viton® O-rings
These are tested at the factory and have some transmission oil in it.
Avoid problems by reading the included card in the gallery,
and once installed ensure the transmission connector is torqued to factory specs!
If not, random codes are likely because solenoid pins aren't getting full contact
