Before swapping, note the factory engine families:
| Transmission | Engine Compatibility | Notes | | :--- | :--- | :--- | | | 2006–2012 V6/V8 | Mercedes-based unit. Strong, but needs input shaft upgrades for high torque (600hp+). Different bell housings for V6 vs V8. V6 Trans does not bolt to V8. | | ZF 8HP (8-Speed) | 2012+ V6 / 2015+ V8 | Requires TCM integration. The bell housing patterns changed in 2015 for the Hellcat/392. Early ZF transmissions (2012–2014) are V6 specific. | | Tremec TR-6060 | 2008+ SRT / Hellcat | Manual swap. Requires pedal assembly, clutch hydraulics, and tunnel modification for the shifter location. | dodge charger engine swap compatibility chart
