Description

4R70W, 1996 up performance pressure spring and valve

Fits ’96-Later units only.

Complaint:

  • Delayed Forward
  • Forward clutch failure
  • Low base line pressure

Cause:

Low line pressure


Correction:

Raise line pressure and increase holding power by installing Sonnax elevated pressure regulator valve kit.

Ford vehicles equipped with 4R70E, 4R70W, 4R75E, 4R75W and AODE units may have delayed engagements and burnt forward clutches due to low line pressure. This can be even more pronounced in heavy-duty or performance vehicles. Sonnax elevated pressure regulator valve kit 76948-12K provides a modified valve and stronger spring to raise base line pressure, eliminating these concerns.

  • Hardcoat anodized aluminum valve combats premature wear
  • Annular grooves help center valve in bore to reduce side-loading

NOTE:

Sonnax valve replaces both styles of OE valves.
