Description
AOD Governor Circuit End Plug Kit, Sonnax 76999-05K.
Fits units mid-’83-later.
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. AOD valve assemblies are designed with an end plug to help retain the lineup and seal the circuitry. When these end plugs wear, circuit oil is lost and shifts affect timing. Installing Sonnax governor circuit end plug kit 76999-05K can eliminate this excess 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, O.D. servo regulator, 3-4 shift (plug or sleeve), and either the 3-4 shuttle or 2-3 backout.
- High-quality aluminum is used to manufacture plugs, designed to resist wear.
- O-Ring on the O.D. 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
- 3-4 Shift Valve
- 3-4 Shift Sleeve
- End Plugs (2) Medium
- End Plug Small
- O-Rings (8) 4 Extra
Symptoms:
- Erratic shift timing
- Oil leaks
Cause:
Leaking valve end plugs in pre mid-’83 units, or worn 3-4 shift valve and sleeve in mid-’83 and later units.
Correction:
Replace worn, leaking valve end plugs with Sonnax drop-in O-ringed end plugs. Manufactured from high-quality aluminum, these end plugs are resistant to wear.
