Overview

The Sonnax AODE-4R75E-ZIP Transmission Zip Kit is designed to address critical pressure losses in the valve body of 4R70E, 4R70W, 4R75E, and 4R75W transmissions.

This kit also includes components to resolve forward and intermediate clutch failure, overdrive servo failure, soft shifts, intermediate roller clutch/mechanical diode failure, and low clutch apply pressure. Installation is straightforward as no separate special tools are required, and it installs quickly. A detailed technical booklet with rebuilding tips, inspection advice, and vacuum testing information is included.
