what transmission to use with new hemi 5.7

swift, one of my homies on here always replying to me.

Totally going EFI, no point in going through all this trouble, dealing with all these hurdles, computer, harness, no distributor, etc etc, just to make it a carb.

Think im going to use hotwire auto too, im assuming they can hack that computer to control a tranny if needed (i know they told me that can program the ecm to ignore the tranny)

DO need a little expalining, controlling it on the dash? whats that mean?
Mind you I have never driven a car that had an OD, that I had to control.....if thats how this works.
