Torque converter crack

I have used Transtar kits and was happy with them, but never used Pioneer before.
I use a solvent (or gas:D) by putting a 2 or so foot section of fuel line on my blower tip, then dip the hose and attach it to the cooler line and hit it with air.
This blows the solvent through those lines and cooler at a high speed so it breaks up the clumps and carries it out of the other line.
I'll alternate between lines a few times because the stuff that builds up in the cooler hides around corners and compacts there.
Blowing it both directions gets that junk that is hiding around corners.
