Sonnax test manifold kit tests internal mechanical sealing ability only; it does not test the integrity of the electrical coil and contacts. See instructions for details.
The leading cause of solenoid failure in ZF8HP45, ZF8HP55, ZF8HP70 and Chrysler 845RE units is an inability to maintain an internal mechanical seal, resulting in a multitude of drivability concerns. Since it is not an electrical failure, it can be difficult to evaluate whether a solenoid is the cause of a particular problem.
Sonnax solenoid test manifold kit 35430-VTK allows quick, easy, cost-effective pass/fail verification of the solenoid's internal sealing integrity, taking the guess work out of replacing solenoids.
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.
