Why use a Dodge 8HP70 instead of a BMW one?
Simply said, in North America, no other variant comes close in terms of price and availability! Yes, it's bigger, but we make it work.
All 3.6 V6 are 8HP45 (845RE). All 5.7 or 6.4 are 8HP70.

- 2015+ Dodge Charger RWD3.6 V6, and 5.7 V8;

- Not compatible with the 8HP75 transmission from RAM 2500HDs;
- Not compatible with 8HP90 transmissions (Hellcats).

What controllers do you recommend?
MaxxECU: If all you want in a transmission that works well for the street, with OEM-like performance, this is a perfect solution for you. With a MaxxECU, you'll need to rent the transmission flashing tool, available on our website, and you're set!
Turbolamik: If you care about launch control, perfect shifts, and endless transmission capabilities, you might want to consider a dedicated TCU. Although more expensive since it's a separate add-on, you'll love the versatility it offers. We even offer remote tuning to get you started!
