Forward Control Valve Kit

KIT FORWARD CONTROL VALVE (AX4N)

Symptoms:

  • Coastdown Neutral after 4th Gear
  • No Forward
  • No 4th
  • Burnt Forward clutch

Cause:
Forward control valve is bent or sticking from the stem, smashing into the retainer clip.

Correction:
Resize the bore and install the Sonnax forward control valve to restore valve function and prevent future problems.


The front stem of the Ford 4F50N, AX4N aluminum forward control valve bangs against the steel retaining clip when stroked. The force of this constant banging often causes the valve to warp and seize in the bore, as well as breaking the OE clip. No valve movement can result in a neutralling-out complaint, no 4th gear or a burned forward clutch. The Sonnax forward control valve kit corrects these problems.

  • Sturdier front spool on valve provides more than twice the spool-to-bore contact area
  • Design prevents valve warpage and/or seizure
  • Annular grooves are added to the spools to properly center the valve and prevent leakage

Note:
Although this valve does not require a reamer, use of the bore sizing tool is highly recommended to quickly and easily resize the bore.
