Technical Valve Body

The Valve Body is an often source of troubles for transmission repair specialists - here our Team work to provide reliable tips and techniques on this complex unit.



Some shops opt to just replace all the solenoids on the valve body. On some models that makes sense as the replacement solenoids are fairly cost effective. For other models, the cost of either OEM or aftermarket replacement solenoids do make it worthwhile to test and only replace the ones that are worn or faulty.
When we talk about testing, we not only need to understand why we are testing it, but more importantly, the how do we test it. The “why” is fairly straight forward, as we want to determine if it is still functioning properly and that we can reuse it. The how to test it might not be as clear, and there are multiple methods of how to test, and sometimes opinions on how to test that are not always accurate.
