How hard is it to fill up the TC's if they are leaking and what type of oil should we put in them to hold off till the recall is complete.

The thud is just caused by play in the driveline. Since its AWD, and there are so many components to the driveline, there are quite a few places where this play can be introduced, and all of them will contribute some. For example, worn carrier bearings (hold the driveshaft) will allow the driveshaft to flex more than it should, allowing play. And the TC contributes some too, and the more worn out the bearings in the TC are, the looser all of the mechanical parts inside will fit, and that introduces play. The lack of oil does not necessarily cause the thud, if you have a lack of oil, its already too late. If the TC is leaking really fast right now, don't drive it. You can't check the fluid level every time you pull into a gas station, b/c you need to have it on ramps or a lift so you can take the fill plug out. Changing the TC oil is not a big challenge (do a search to find out how, I've written more than enough here
), it takes the same stuff as the transmission, like 75W90 Gl-4.
