Re: What did you do with your truck today, Part 3

nvdone's sig said he has M21 trans. GM in it's wisdom never drilled the cast lug where a drain plug would go on some generations of Muncie. It was common back in the day to drill and tap them on the car. Same trans had a low area at the bottom of trans that would not drain regardless, GM tossed a magnet in there. The only way to clean that was take the trans apart.

if your willing to drill and tap for a drain plug, I'd try using one of the small super magnet on extendable wand pickup tools through the drainplug hole to see if you can pull the shavings off the magnet.
