Description & Specs
Some typical problems in vehicles with a Ford A4LD transmission are 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 boost valve kit S56741BD-1K replaces worn parts and matches the OE-style, low-ratio valve.
