BOOST VALVE AND SLEEVE KIT
LARGE RATIO WITH O-RINGS
BY: SONNAX
 
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 S56741B-1K with O-rings replaces worn parts and offers higher line rise than the OE-style, low-ratio valve.
