ZF transmissions have had this issue for years. If you do a rolling stop you catch the transmission doing a second to first gear downshift. Then you suddenly ask it to go and there is that delay.
I don't think it is a shift issue, It would def be 1st. gear...going from a rolling 1 or 2 mph to normal drive it is an engine lag....However someone else on another forum wrote this....

503000 Automatic Transmission Engagement Concerns
Issue:
Powertrain Transmission Module Learn Adaption routine has been instated on SDD/Pathfinder.
Cause:
The routines have been installed after enhancements were made to each, following feedback from the market, as of Version 152 Patch 2
Action:
Should a customer contact a retailer regarding Automatic Transmission shift quality on 8 Speed variants, please follow the routine below in the first instance after fully understanding and confirming the customer concern.
1.Ensure Transmission and other relevant Powertrain control modules are at the latest software level available.
2.If there are any DTC’s read by the diagnostic tool, resolve them, before proceeding.
3.Using the routine, “Powertrain – Transmission control module adaptions”, ensure that all the clutches have at least 3
adaption counts.
4.If any of the clutches have less than 3 adaption counts, carry out an adaption drive cycle using, “Powertrain Transmission Module Learn Adaption” to achieve a minimum of 3 counts on each clutch.
5. If the shift quality concern is still present carry out an adaption drive cycle using, “Powertrain Transmission Module Pulse Adaption” routine to achieve a minimum count of 3 on each.
5.If all the clutches have at least 3 adaption counts and all Powertrain modules have the latest software, should there still be a shift quality concern, raise a TA, with a screen shot of your adaption status. The TA will advise further help in order to resolve the issue
