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.

• Must be used with Sonnax vacuum test stand VACTEST-01K
• Test solenoid sealing reliability with vacuum by inserting solenoid snout into Sonnax test manifold
