Hey all, I am interested in getting a different transmission pan that has a drain plug to aid in changing of the fluid. I tow 2-3k pounds 3-4 days a week so I think changing the fluid more frequently could be preventative maintenance. Anyway, I understand some of these pans which have the drain plugs are deeper, or have cooling fins or tubes. Anyway, has anyone used these, and are their any benefits or problems with them? Thanks.
