Was sooo close....

Yea it was a little circular style rubber piece with a little piece missing... When I saw all the sparkle in the fluid I knew it was done...Lol... In a few weeks I'll pull it out. What's the best way to clean the TC?

Short of cutting it open, there is NO WAY you can properly clean a converter out. Foreign material will compact in the vanes of the pump and the turbine and no amount of flushing with solvent will get that stuff to move. Also, the transmission oil cooler in the rad, or any external cooler will have the same junk, and need to be attended to.
