most people say no, draining the torque converter may cause a sludge ball to break loose. Keeping clean fluid circulating will clean out any sludge over time.


Change that filter if you haven't already.


One thing that is tricky is getting the fluid level correct when you refill it. New fluid is hard to see because it's clear, the engine has to be running when you check it, and

the level when COLD (on my 85 300td) is actually 10mm BELOW the mark. After a long drive, the fluid fully warmed, it will read at the normal level. There has been much discussion on that topic.
