FCA doesnât use ZFâs 8HP50. They build & install the copycat 850RFE along with their own programming. Thatâs why they feel a bit different to you because they are different.I'm familiar with the ZF-8HP50, as this is the third vehicle in my direct family with the transmission. I also know that the way it's programmed in the JL sucks in comparison to other cars (specifically BMW). I have no doubt that the transmission itself is capable of awesome quick shifts, but in the JL they always seem to be a bit lacking and sluggish (not compared to a JK, but compared to other ZF 8-speeds).
The 3.0 using 8HP75 will be the first actual ZF transmission in a Wrangler.
