torque converter plug
When doing a trans fluid change, I will be draining my torque converter as well. Now Im reading you have to put in a new plug when you do this, but im also reading the conv is a balanced unit so putting in a nedw plug is bad......... Any info to as which one is not true????

Don't bother messing with it. Follow Mark's directions here Changing ATF Fluid in a E4OD and 4R100 transmission .: Articles and it'll all flush out without the need to pull and replace a plug (they stopped putting them the 01 and later models even). Mark is a retired Ford transmission guy and knows his stuff.

I know 100% that Mark knows his stuff beyond a doubt.
But, That said I personally am not a fan of flushing.
I drained my pan, cleaned it, replaced the filter, drained the converter, I certainly re-used the plug-why not? and then re-filled my trans with Mercon V up to the full mark-I put in 6-7 quarts and started engine for about 60 seconds then brought the level up to the full mark with the rest.
YES, there was probably some old fluid in the lines and cooler, but thats fine with me.

I think were you may be getting confused is some people have been asking about drilling a hole in their converter and then tapping the hole and installing a plug. That can affect the balance.

Ok I didnt think it made sense to replace the plug but better safe then sorry. And I have a 2000 so supposedly it has the plug. Its the cheaper of the two routes to change the fluid in te pan and conv then a full on flush so thats the path i have to take for the time being. THANKS

Your torque converter had a drain plug when it left the factory. Either you haven't found it or the torque converter has been replaced with a later one.

The kid I bought my truck from said he "replaced the conv because he felt it going out" so that being said I should get under there and look first. You know what they say about assumtions.......
