General Motors 8L90 Overhaul Part Three: Valve Body Overhaul

This video is part three of a three part series on the overhaul of the GM 8L90 transmission. In this video, I cover the valve body in depth. Not only do I disassemble, inspect, and identify all the valves, but I also cover the additions and improvements found from Sonnax and Transgo. I cover what they changed with their components and how it will likely change the operation of the transmission.
