I have a custom jeep I have been working on. I have a 8HP70 transmission in it. Its a 4WD unit from a 2021 5.7 Grand Cheokee but the TCM was bad so I used a TCM from a 2018 Charger SRT8. The transmission shifts kinda weird so I was wondering if ssomeone can send me a stock transmission tune file for a 2018 to 2021 Grand Cherokee or Durango SRT8 so I can compare ? I've already checked the repository.
the tune changed in 2018
(2018-2022 are the same)

oh - i misunderstood what you were asking
the trans tune for hp70 that was behind 5.7 is completely different than one that is behind a 6.4
different power band
*compare copy paste or pay dodgeboy to fix it
that is his specialty

Hey Ingeld!
Be careful whom you listen to here, because people respond to your post but:
- Do not know the difference between a 5.7L and 6.4L
- Do not know the difference between 2WD Dodge and 4WD Jeep
that ^^^ is the guy i was steering you to. neither of those is a 5.7 or a 4x4 tho. not sure why he shared a 6.2 and a 6.4?
here is a 5.7 hp70 tune for ya:
it is a 2017 and like i said dodge changed the tune in 2018. the later stock tune is better but they both need work imo
