I’m a newbie to the gen III swaps. I have a 96 Dakota 2wd that I’m putting an 08 5.7 in. The truck was a 3.9/42re, it has the o/d button on the dash. Can I use the 42re if I have it built to handle the extra hp/tq of the hemi? I’m just not sure how the electronics work to control the trans. I also have an a500 trans. That I could use. Should I find a 46re? Or? Thanks!
