Converter flush?

Is it possible to flush a converter without cutting it open?

Most Transmission repair shops have a converter flush machine. Just beware that they are meant to flush burnt oil and have trouble with gritty metal debris. If your trying to flush metal out, it is probably better to have the converter cut apart, so everything can be clean throughly, and possibly replace the bearings.

I've been looking for a shop in western Canada to flush a converter, but most have abandoned the practice. Either they install new or reconditioned convertors, or cut them apart and rebuild them.

I think it's becoming a "lost art".

As Russ said, you can flush the oil out of one ,but most of the debris hides up under the weld seam at the radius high point. I doubt that will ever flush out.
If you don't have a drain plug (highly recommended) the best you can do is, first,
set the unit on the bench and slip a small vinyl hose through the hub and all the way down to the pilot area, and start a siphon going over the edge of the bench.
Once you get most of the oil out, then refill the converter with a mild solvent like mineral spirits.
If you have a trans input shaft laying around, you can then spin the turbine for a while to stir up the fluid. Siphon it out again , then blow it out with air until mostly dry.
That's about the best you can do , my friends.

Thanks for the replies. Unfortunately there’s more junk in there than I was hoping to find. I’ll send it back to ATI and get it done right.
