Symptoms:

Erratic shift timing
Low line pressure
Low throttle pressure

Ford A4LD transmissions often have shift timing problems due to shift or accumulator oil circuit leakage caused by leaking end plugs in the valve body. A4LD valve assemblies incorporate end plugs to retain the valve train and seal the circuitry. As end plugs wear and circuit oil is lost, shift timing suffers. Installing Sonnax O-ring end plugs can eliminate this circuit leakage.

O-Rings provide a positive seal
High-quality aluminum resists wear
Kit 56947-14K includes replacement o-ringed end plugs for the 1-2 shift valve, 2-3 shift valve, governor coast boost valve, 1-2 transition plug, throttle pressure boost valve and intermediate servo accumulator valve
