What do you do when no amount of pounding on a transfer punch will remove the transmission?
I assume you are using talking about a 7mm transmission. This is the system that has worked the best for me. In a scrap piece of wood, drill a hole that is as close to the diameter of the transmission as possible. On a band saw, cut a straight line through the length of the hole so that it can be spread apart (similar to a collet). Buy 2 washers with a 1/4" hole in the middle. Place both washers over the transmission. Insert the transmission into the hole drilled into your scrap piece of wood and push it down the transmission until the block is seated about 3/16th-1/4" away from the end of your barrel. You should now have your turned barrel, 2 washers over the inserted transmission, a small gap, scrap wood over the transmission. Put a clamp on the scrap wood so that it pinches the transmission and won't slide off. If you've drilled your hole the right size, it shouldn't damage the transmission at all. Place one of the washers against the barrel, and the other against the scrap block. Use a flat head screwdriver to pry the two washers apart. This prying motion will push the scrap block and the turned barrel further apart also. Since the transmission is gripped by the scrap block, it will be pulled from the tube. To release the transmission from the scrap block, insert the screwdriver into the slot cut the lenghth of the hole and lightly twist it to widen the hole. This should free the transmisson. Hope this helps.

It's unusual, but I've had a couple slims that I couldn't get the tranny out with a punch and had to resort to just drilling it out. I also have one of those slim disassemble tools and I had used it to remove a stubborn tranny and no only did the rod not remove the tranny, but the rod also got wedged inside the pen..to this very day I still have the pen section with rod stuck in it.
