Cause:
Loss of oil pressure due to worn components in critical oil circuits.
Correction:
This Sonnax reverse boost valve kit has upgraded materials and tighter clearances to prevent wear and restore proper hydraulic control.
Sonnax Zip Kit targets the root cause of multiple complaints by sealing the critical circuit pressure losses in the Toyota/Lexus U660E and U660F valve bodies. The kit contains uniquely designed parts to prevent the loss of pressures within the main line, clutch apply control and lockup control circuits. The kit also seals multiple circuits known to suffer from end plug leakage or poor checkball sealing. 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.
