Does anyone know what size of bolt and thread that the drian plug for the torque converter on a 300D. The head of mine stripped off and I am getting ready to easy out it. I am looking for a bolt to plug the hole until my new drain plug arrives from the dealer.

Thanks

Scott

10mm is a common size. But 300D's came with a number of transmissions. On some transmissions, the torque converter plug is the same as the transmission pan plug. If I had to use a field expedient, I would much rather use it in the pan than the converter.

Most auto parts stores carry a variety of replacement plugs.
