How to Test the VCV ( Vacuum Control Valve ) for Proper Operation - On Demand Video

Includes theory on how it controls transmission shifting and test procedures with it hooked up to the vacuum system with the engine running.

Kent will explain the theory of operation in simple terms, why it is so important for proper transmission shifting performance, and how to test it hooked up to the engine's vacuum system with the engine running. This valve is found on 1978 to 1985 5 cylinder turbo engines and on the 1980 to 1983 non-turbo engines. If it is not working properly you will never get your automatic transmission to shift properly. If it does not test successfully you will have to find a valve replacement and they are only available used.
