Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits

Sonnax kit SC-AODE-1 has been discontinued and replaced by Sonnax Zip Kit AODE-4R75E-ZIP.
Sonnax Zip Kit AODE-4R75E-ZIP targets the root cause of multiple concerns by sealing critical circuit pressure losses in the valve body. The kit contains uniquely-designed parts to prevent the loss of pressures within the main line, solenoid regulator, converter clutch and overdrive servo circuits. The kit also contains components to address forward and intermediate clutch failure, overdrive servo failure, soft shifts, intermediate roller clutch/mechanical diode failure, and low clutch apply pressure. No separate special tools are required for installing these parts.
The Zip Kit quick guide provides clear and easy instructions on one sheet to get the unit sealed up and back on the road quickly. In addition to general rebuilding tips and technical information, the technical booklet included in this kit contains vacuum testing information and locations at other key areas of the valve body.
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.

It's easy to restore and extend vehicle shift quality with Zip Kits. Uniquely designed, drop-in Sonnax parts target the root cause of valve body complaints and stop critical circuit pressure losses in the most common problem areas of the transmission.
