904 Transmission Stopped Going Into Gear

I hardly ever find large enough particles in the valve body to hang up any valves. V8 drums have a higher ring slot so they can hold more clutches, but if you'll notice the lower forward clutch pressure plate is thinner at the edge, allowing one more plate when used at the tops. My supplier charges me $6 each. Always match the forward drum to the pump. Some only have two rings.
