Description

A4LD Boost Valve Kit, Sonnax 56947-02K. 

O-Ring Style, High ratio

Typical problems in vehicles with a Ford A4LD transmission include low line pressure in forward or Reverse, soft upshifts, delayed Reverse and poor modulator control. These complaints can often be caused by a worn boost sleeve, which allows Reverse and/or TV pressure to cross-leak or exhaust. Sonnax high ratio boost valve kit 56947-02K with O-rings replaces worn parts and offers higher line rise than the OE-style, low-ratio valve.

  • High-ratio valve with O-rings offers higher line rise than the OE valve
  • Hardcoat anodized aluminum valve combats premature wear
  • Sleeve manufactured from highly wear-resistant aluminum
  • Drop-in Zip Valve parts install quickly and easily

Symptoms:

  • Delayed Reverse
  • Soft upshifts
  • Low line pressure in Forward
  • Low line pressure in Reverse
  • Poor modulator control

Cause:

Worn boost sleeve allows Reverse and/or TV pressure to cross-leak or exhaust.

Correction:

Sonnax drop-in boost valve kit restores hydraulic integrity to the bore.
