09+ Challenger TR-6060 six speed mate to 03-08 5.7?

Yep, nice transmission. Get a CORE shifter and you'll need the Driveshaft Shop CV style driveshaft. It also doesn't have a speedo output of any kind so you'll need to address that. I put magnets on the driveshaft adapter and picked up the signal with a universal cruise control sender. Then conditioned it with a junkyard vss buffer module from a GM car and fed the signal to an Autometer speedo.
