2015 3.6 задний дифф с LSD ?

Подскажите, задний дифференциал у пентастара 2015+ с LSD или без ?
Хочу поменять масло 75w90, но не могу найти однозначной информации о типе диффа. И нужно ли туда в итоге лить limited sleep присадку итд

Mopar 75W-90 GL-5 Synthetic Gear Lubricant (68218655AA)

Update:

Any 6-speed R/T will be LSD diff

Same for SRT models, either trans = LSD

For a period, '12 — '14 R/Ts with automatics had LSD as option — look for the finned bright aluminium case. If its the smooth case that's dull gray (its cast iron housing) that's the non-LSD open diff.

Going forward to '15:

SRT, and SP models have LSD diffs with either trans (case has fins on the lower section)

R/T 6-speeds only get LSD diffs

SXT or R/T automatics are open diffs.
