what transmission to use with new hemi 5.7

I noticed the nag1 is omitted. I wish I could post the pictures of everything we have. Unfortunately we can't at the moment. The NAG1 is the best transmission to put behind a new hemi. It is exceptionally well built, you can build it to hold a nearly unlimited amount of power. It is geared well.

I know everyone shys away from it because the electronics, but I am telling you we have the electronics worked out. The 545 is JUNK, you can break them with a stock 6.1. Plan on spending $2000 to buy a nag1, converter, and electronics. It will hold 550 wheel horsepower in stock form.
