Product Description
A4LD O-Ringed End Plug Kit
Sonnax Part Number: 56947-14K
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-ringed 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
- Components are also available individually in Sonnax end plug kit 56947-SML
- Drop-in Zip Valve™ parts install quickly and easily

SYMPTOMS
- Erratic shift timing

CAUSE
Valves cycling in various bores strike the end plugs, creating excess clearance between plug and bore. Worn plugs can leak critical throttle and Reverse pressure.
CORRECTION
Sonnax drop-in O-ringed end plug kit eliminates leakage at the bore plug.
