Anyone know where you can find a drain plug kit to install in a th350 pan? Tired of draining it the hard way.

I've had pretty good luck with the ones from the "Help" section at Advance Auto. You'll need to drill a 1/2 hole to install. Down side is they stick up in the pan a little so not all of the fluid will be drained. I'd suppose a braised in one would be better if you have the skills to install it.

What about getting one from the bone yard. Many TH350's came from the factory with a drain plug.

B&M offers them as well

Autozone was selling them. Hanging on a hook near the "chrome performance" stuff. If not, try JEGS catalog. B&M as well as others have them.
