Vehicles with Ford AOD transmissions often have shift timing complaints due to governor or accumulator oil circuit leakage caused by leaking valve end plugs in the valve body. Most AOD valve assemblies are designed with an end plug to help retain the lineup and seal the circuitry. As these end plugs wear, circuit oil is lost and affects shift timing. Installing Sonnax O-ringed end plug kit 76999-SML can eliminate this excessive leakage.
Replacement plugs are included for the following valve applications: 1-2 capacity modulator, orifice control, O.D. servo regulator, and either the 3-4 shuttle or 2-3 backout.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
