Transmission swap

[outboardguy]

Hi..I'm putting a 2006 5.7 hemi out of a charger, into the old car. Donor car has a nag1 trans, which apparently is almost impossible to make work without spending less than a million dollars. Can I put a 45rfe or 545rfe behind it and change the ecm with my hp tuners to mske it work?

You have many options regarding which transmission to run. Here are a few among the many you could pursue once you decide how much floor/ chassis modifications you plan on making.
