Product Description
A4LD Boost Valve Kit | O-Ring Style, High Ratio
Sonnax Part Number: 56947-02K
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
