That is correct. Mercon is Ford's version of GM's dexron. The Dexron is what you want. If you go with the later Dexron VI, it is semi-synthetic, and is backward compatible and will mix with the older fluids and is a upgrade in all Dexron/Mercon applications.

Most of the c6 torque convertors have a drain plug, check and see if yours does. If it does, that is the easier way to drain it. You could ahead and leave it empty, or put some in it. This draining procedure can be done when the tranny is installed in the truck. With the trans being empty also, I would buy 13 quarts of fluid. You only need 3 or 4 quarts if you drain the pan only.

The reason is there are plastic washer bushing and if no oil is there on first start up they run dry till oil is pumped in there.
I have always add 1 qt before install.

When you do this procedure in the truck, you drain it and the trans completely, and then add about 4 quarts back in the pan and get ready with the other 8 or so to pour in once the engine is started. There is no way to add some just to the convertor when doing this in the truck, but I suppose this is a used convertor and will have oil residue enough to lube it for a few minutes. I have done this several times over the years with no problems.
I can see pre-lubing a brand new never used torque convertor before installation.

That's sufficient. It's actually two quarts more than you have to put in the converter.

If you are saying pour it into the converter then yes.
As I posted before 1 qt min. is what I pour in to any converter used or new. This way I know it has something in it on start up.
Just a habit I got into when first started working on car & trucks.

Here's a related question: Since I don't know if the C6 coolant lines are in the same locations as the ones on the C4, can I use compression fittings to splice lines together, or should I use trans cooler hose?
