Required tool kit 56947-TL is no longer in production. Check with your distributor for availability.
Typical complaints about vehicles with Ford A4LD transmissions include soft shifts, low line pressure and/or converter apply problems. A worn valve body bore at the pressure regulator valve can often cause these complaints. Line pressure is allowed to leak to exhaust, preventing the valve from stroking properly and feeding the converter apply circuit. Sonnax oversized pressure regulator and boost valve kit 56947-06K restores the hydraulic integrity of the circuits.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
