Yes, a drain plug is a handy addition to the tranny pan and something I did to several of my cars. When installed by knowledgeable people, the drain can make a nasty and difficult job, clean and easy. Now, "common sense" would dictate, that after you drain the fluid from the pan, the next step would be to remove the pan to clean it well and change the filter!

(Unfortunately, not all car owners have common sense)
Did you ever wonder why the factory chose not to put a drain plug in the tranny pan? The logic behind that decision was, if drain plugs were installed by the OEM, most people (including quick lub techs) would simply drain the fluid and refill the tranny, without changing the filter.
(This procedure would increase warranty claims!) Big $$$
Now, you ever wonder why transmission failures are more prevalent after a “Quick lub flush”. Could the new fluid (Unlikely) cause it, or could it be from not changing the filter and cleaning debris from the pan? (More than likely)!
