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 ;) ).

Great video and insightful! Got a quick question: in my 2015 Hyundai Genesis g80, no DTCs, TCM updated, ATF changed multiple times, all solenoids replaced, wiring harness and Transmission speed and temp sensors replaced, however I still get harsh up shift from 4th to 5th gear only, and sometimes from 2nd to 3rd gear. They are operated by 35RC solenoid which is already replaced. Could the problem be inside the valve body? What do you think? Thx!
