leegreen - you're right an m21 does not have a pan. I think it was about '68 that gm finally got smart and put in a drain plug. You can drill and tap a hole for a plug with the trans in the vehicle but that scares me. I may just have to drop the trans and do a refresh including installing a drain plug this winter. Using a magnet on a wand might be a good idea.
