i recently had my engine out and then got busy with other things for about 3 months. I finally reinstalled the TC and engine yesterday, but forgot to refill the TC with ATF fluid before reinstalling (I turned the TC upside down when I pulled it and drained some of the ATF fluid out-- there's of course still some in there as it's pretty much impossible to drain it completely without a siphon, but the level is definitely lower than it's supposed to be.)
So my question is, is it safe enough to just refill the tank with ATF while running the engine until enough of the new fluid has been pumped into and through the TC? Or will not having refilled it outside the car cause damage if I try to do this?
Thanks

To add on to my previous post, after reinstalling the TC I spun it around on the input shaft splines to make sure it was fully seated, and it is but it made a very noticeable "grumbly" sound when I spun it. Is this simply because I have not refiilled the system with ATF yet, or is there another problem? TBH it almost sounded like it was rubbing against the bell housing, but it spun freely so I have no clue. Thanks for everyone's help!

Sb,
    You have to fix both the outer shell and internal impellor to prevent a certain amount of "touching" as they are fairly close machined. So, onto the first q. Yeah - just keep your ATF topped up. Check it regularly. With a half or less full converter - expect aeration and subsequent "bleeding" off of air bubbles for a while at least.
