C4 Trans questions

[tarafied1]

So I have this 66 Mustang with a C4. Car sat over 30 years. Front was wrecked and been cut off so it sat with no front clip and radiator. Trans cooler lines were open to the atmosphere. Anyway, trans fluid looks orange and no longer translucent so I think it has water in it. I drained the trans dropping the pan but the torque converter doesn't have a drain plug. (first time Iv'e encountered this).
ANy ideas how I could flush converter without dropping the trans? I hate t fill trans with fresh fluid and have still a quart or two of bad stuff in the converter.

Other than dropping the converter out, no. Maybe Terry has some ingenious way of doing it.

You give me far too much credit, I think!

I couldn't think of a way so I just filled the trans. I'll drive it a bit then flush it again.

Flushing a auto trans.
drain the sump and disconnect the return line from the cooler at the trans.
plug the sump , fill as much oil as you have drained.
start the engine and pick up the oil comming from the return line till is no more and shut the engine off.
you can do this twice if nescessary.
connect the return line and fill to max level with running and warm engine.
