The leading cause of solenoid failure in Ford 6R60, 6R75, 6R80, 6R100, ZF6HP19/26/32 (Gen. 1) and ZF6HP21/28/34 (Gen. 2) 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 95430-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


Manifold Usage
Ford 6R60, 6R75, 6R80, 6R100 solenoids function very similarly to the the ZF6 Gen. 1 versions (although with a significantly lower failure rate) and can be tested using these manifolds, though the colors differ. See chart below for reference:
