Eight Speed Automatic

Fitting the transmission can be done but there will be a LOT of cutting and welding because this transmission is gigantic. The biggest problem is the electronics of it all. The trans is fully electronic, even the shifter! You'd need to either install an entire wiring harness from a donor car or find some other way to fool every one of the sensors involved that everything is in place and functioning normally.
The Wife and I have a 2015 Challenger R/T with this transmission. It is a great unit but until DiabloSport or some other adventurous soul learns to make a stand-alone computer for it, it is impossible to retrofit into an older car.
