They do a badass NAG1, which is found in the cars, and based on a Mercedes transmission.
Easy way to build a monster trans for the 300 challenger and chargers, is to use the OEM Mercedes internals. Supposedly, thats what all the NAG1 builders do.
The Chrysler 45RFE, and 545RFE, is based on the old school Torqueflites, albeit with several modern modifications.
