Missing drain plug?

[rockwall]

I have owned a clark ranger 664 for 8 years, I knew it was leaking ATF a little but not excessively. I noticed the other day a drip coming down the bottom center of the torque converter and dropping onto the front differential. It varies from a drip to quite a few drops and then no dripping at all. I think it is coming out of a drain plug hole in the front center of the converter case, I can feel threads I think. But there was no plug in the hole and I believe there hasn't been one since I owned it. The machine works fine, the only thing I have noticed is, on a cold day it takes maybe ten-15 minutes for it to warm up enough so it will move when I shift it into forward or reverse. Could this plug be missing all this time and it work fine?

yes, the converter case is dry.......prolly a seal is dripping, keep check on the fluid level and run her.

I've noticed sometimes it leaks quite a lot out of the drain hole. Not too often but sometimes.
