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 governor circuit end plug kit 76999-04K can eliminate this excessive leakage.
Replacement plugs are included for the following valve applications: 1-2 accumulator, 1-2 shift, 2-3 shift, 1-2 capacity modulator, orifice control, OD servo regulator, 3-4 shift (plug or sleeve), and either the 3-4 shuttle or 2-3 backout.

Plugs have been manufactured from high-quality aluminum designed to resist wear
O-Ring on the outside diameter prevents leakage between the plug and the valve body
Plugs have a standard 8-32 UNC threaded hole for assistance in installation and removal
O-Ringed plugs are more durable than knurling the O.D. of the original plug
Drop-in Zip Valve™ parts install quickly and easily
