Just when you think electrical diagrams are a PITA to read, now you get these nifty fluid flow diagrams to figure out. The ones for our cars are okay, but the last one is off a 1995 Chevy C2500 and its a little easier to read because you can visually see the transmission. Kinda cool! I was trying to figure out what valve causes the valve body buzz on some of our cars while in Neutral and I ran across these.
