Description
4L60E / 4L65E / 4L70E Valve Body Vacuum Test Plate Kit, Sonnax 77754-VTP.
A worn valve or valve body bore can result in incorrect pressures in the transmission, which may lead to poor performance or failure of the transmission. With the proper equipment, you can efficiently determine if a valve/bore is worn or verify if a valve repair was performed correctly through vacuum testing. It’s an easy diagnostic technique that yields repeatable, numerical results for comparison and documentation.
