Sonnax kit SC-E4OD has been discontinued and replaced by Sonnax Zip Kit E4OD-4R100-ZIP.
Formerly a popular Sure Cure® option, Sonnax Zip Kit E4OD-4R100-ZIP includes added components that extend the coverage of this kit to include later applications. And, like all Zip Kits, no reaming or special tools are required.
Sonnax Zip Kit E4OD-4R100-ZIP targets the root cause of multiple concerns by sealing critical circuit pressure losses in the valve body and pump. The kit contains uniquely-designed parts to prevent the loss of pressures within the main line, accumulator control, line pressure modulator and lockup control circuits. The kit also contains components to address overdrive planetary and piston failure, forward clutch failure, soft shifts, low clutch apply pressure, unit end play, and lube and bushing failure. 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 and pump.
It's easy to restore and extend vehicle shift quality with Zip Kits. Uniquely designed 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.
