A worn valve or valve body bore can result in incorrect hydraulic pressures, leading to poor performance or failure of the transmission.
Vacuum testing is an efficient way to evaluate wear and the effectiveness of repairs. Measure the integrity of a circuit by applying vacuum and comparing the vacuum held by that circuit to a known maximum standard.
Sonnax vacuum test guides identify valve body areas most prone to wear and the location to test these circuits in a specific unit both before and after making repairs.
Proper equipment and calibration is essential for accurate vacuum testing!
The Sonnax vacuum test stand kit is a great alternative to building your own testing rig that includes an assortment of testing tips, an anodized test stand to withstand years of use, plus easy-to-follow instructions for assembly, calibration and use.
What should my vacuum test results be?
While a properly calibrated and maintained test stand will give consistent vacuum reading results, evaluating those results requires establishing your own pass/fail standards. Detailed information on vacuum testing and establishing pass/fail standards can be found in the Sonnax vacuum test stand kit instructions.
