Loss of oil pressure due to worn components in critical oil circuits and/or pressure switch failure.
Recover hydraulic control, restore normal shift operation and save the transmission control unit by installing Sonnax Zip Kit.
Sonnax Zip Kit 6T70-ZIP targets the root cause of multiple concerns by sealing critical circuit pressure losses in the first generation GM 6T70 and 6T75 valve bodies. The kit contains uniquely-designed parts to prevent the loss of pressures within the main line, clutch apply control, actuator feed and lockup control circuits. The kit also seals multiple circuits known to suffer from end plug leakage or poor checkball sealing. No separate special tools are required for installing these parts.
Replacement pressure switch seals and laminate discs in this Zip Kit address various trouble codes related to failures of fluid pressure switches internal to the transmission electro-hydraulic control module (TEHCM). The installation tools included in this kit allow rebuilders to perform switch repairs quickly, easily and safely.
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.
Before installing pressure switch repairs, test switches to verify proper electrical operation. This Zip Kit repairs laminate disc and seal failures only, it will not rectify electrical breakdown. See instructions for details.
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.
