The torque converter clutch (TCC) solenoid in a 1993 Dodge Caravan isn't located in a single easily accessible spot like a standalone component. It's an internal part of the
transmission's valve body. Therefore, you won't find it just sitting somewhere under the hood or easily reachable externally. To access it, you would need to remove the transmission itself.
In short, you'll find it inside the transmission's valve body, which requires a significant transmission disassembly to access and replace. Any repair would best be left to a professional transmission shop.
