Transmission swapping

Is it possible to use a transmission from a 5.4 2wd, in
my 4.6 ? Truck is a 2006.

Both are the same bell to engine pattern. Check the input shafts for spline.

Is the 4.6 a manual transmission? Are they both 4x2?

If you had a failed trans, you might want to go for a new TC specific to the engine once you confirm things are the same on the input side.

I do not know what you will run into with the controls. I can't imagine they are drastically different but I also can't imagine a 5.4 shifts at the same mph/rpm as the 4.6.

Stand by, there are thousands here who know more than me.

Yes, that will fit fine if the 5.4L trans is a 2004 or newer.
