I'm in the process of removing my automatic transmission (I believe it's a C4). The manual says to spin the crank until the torque converter drain plug shows up. I've removed the drain plug cover plate thing so I can see the torque converter bolts, but I can't find my drain plug. All the bolts seem to be the torque convertor bolts to bolt it to the flywheel. Is it possible my converter doesn't have a drain plug?
