Sonnax TCC Zip Kit 8L45-8L90-TCC-ZIP targets the root cause of multiple converter-related complaints by sealing the critical circuit pressure losses in the GM 8L45 and 8L90 valve body. The kit contains uniquely designed parts to prevent the loss of pressures within the lube, converter limit, line pressure and converter apply circuits. These solutions target wear that results in lube-, cooler- and converter-related complaints. No 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 fast. 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.
