I have a 1973 Challenger. I have donor vehicle 2007 Chrysler 300. 5.7 hemi nag1 trans. Can I make it work with the chrysler harness? I've heard about trans shifting issues because it takes data from the speed sensors. I'm willing to spend money but I would like it to be less than the 2k aftermarket ones available. Any help would be appreciated.

You need quite a few things to make the NAG1 work. It’ll be very hard to do for under $2,000z If you used a manual transmission or old school automatic, you could have the swap running much cheaper
