3.06 final drive swap - game changer!
I don’t think the Chrysler has the same housing so I doubt you can just bolt the entire chrysler unit in but I may be wrong if you can that would be the way to go if you can find one with a lsd and just bolt the unit in

The diff is the easy part. Good luck on the TCU/ABS/ESC programming.

TCU tuning is now pretty available - @5soko in NY/Tri-State does it, and I can also do it. Couple other places here and there as well!
Thanks!

Thanks!

However what we’re talking about here is getting a shorter final drive gear to get along with the TCU, ABS and ESC units. 3.06 modified vs 2.82 stock. Without correct coding for all three, it won’t work at all. (see above)
Are you saying that EC can do this for the TCU? And could you explain how exactly please? What about the other dependent control modules?

Can someone let me know if the have a similar TCU and have had this swap done successfully? If so, please let me know who I should get in touch with to have my TCU recalibrated?
Getting ready for a Hurricane tonight, so I'll be hunkered down waiting for an answer!!!

I'm not sure. I understand when you say the bigger Gear needed to be honed inside the Chrysler Diff?? Had not the bigger gear come from the Chrysler Diff in the first place???
So Again, did you take the Ring & Pinion from the Chrysler SRT8 and swap into the AMG Diff? Please read my previous post and answer accordingly so we can all be certain of how to go about making the plunge to make this conversion.
Ok so I had the diffs removed out of both casings because i needed to mate the AMG lsd to the Chrysler ring n pinion...which then meant homing them both as one unit into the Chrysler casing. I hope that helps to clear things up. You do however need to use the AMG flange which connects the diff to the propshaft.
Here's a quote of mine from the OP:
"After the shop had done the work (new bearings installed of course), it was time to finally fit the 3.06 ring gear and LSD into the Chrysler casing which now has the AMG propshaft flange."








So the question wasn’t answered either which is interesting. Do you really think the required TCU coding for this can be done via OBD2? What else, probably ABS/ESC too? I didn’t think so but I’d be happy to be wrong here...

Worth mentioning though, I remember a little while back that RENNtech claimed they could tune the TCU on the W212 turbo cars via ODB (torque limiters and all that jazz, I didn't see anything about gear ratio's though). Maybe something exists, but it hasn't gone mainstream yet

In addition to all the benefits of a TCU tune like faster times, better, smoother shifting, higher line pressure, etc. You do have the ability to change your final drive if you'd like to something more aggressive. All software changes, all done through the OBD2 port.Let me know if you have any questions!
Thanks!

3.06 or 3.27 with a 7600rpm auto-shift would be so nice going WOT from 70mph-1000mph.




When are you guys back in CA - this can only be done in-person, right?
