Where is the drain plug for torque converter on a 2006 Chrysler town and country?

The 2006 Chrysler Town & Country doesn't have a drain plug specifically for the torque converter itself. The torque converter is an integral part of the transmission, and the transmission fluid is drained and filled as a single unit. There's a drain plug on the transmission pan, and that's where you'd drain the fluid that also lubricates the torque converter.
