This is part six of a seven part series on how basic automatic transmissions operate. In this video I explain the purpose of a valve body and the common valves found in a valve body. I cover how a common switch (shift) valve operates in conjunction with an electronic solenoid. I also cover how constant and variable pressure regulator valves operate. This video is intended to teach a student or a technician that's new to automatic transmissions the basics of automatic transmission valve bodies. For more detailed explanations of valve bodies, refer to the videos I have on specific transmissions.

Had my 1997 toyota Corolla transmission rebuilt, I was there to watch the guy rebuild it and he changed the clutches but didn't touch the valve body. Now it slams into reverse, I'm thinking about a diy valve body cleaning because I do alot on my car myself, but it's quite intimidating. But great teaching

Once in a blude moon, our Mercedes 2008 ML 350 has gotten "stuck" in low gear where re-booting the car (off/on) fixes the issue. Asked the dealer what the cause could be. They said, "likely the valve body, maybe easy fix with new solenoid, etc.". I had no idea what a valve body was or how it worked. Found this video and, tada!, wowza!, great tutorial! Muchas gracias! ( I noticed you using the Spanish phrase, "muy bueno" in another vid ;) ).
