Haha I bought it off of a forum member Felix 808. He commented a few posts back. I still haven't installed it due to weather and now this odd trans issue :/

That's great... I have been looking for a manual tranny (vlsd) "sport" rear diff pumpkin. Even Felix 808 has tried to help me locate one with no luck.

Mine had been doing this with only 12k on it but after changing oil in the diff last week it all went away.

Sorry for not updating this sooner. I did get my Z back from the dealership and two different technicians told me that the popping/jerking was considered "normal" operation of the 7AT. To an extent I will believe that but, I did ask them to document my visit thoroughly and that when the problem becomes more consistent (which over the hot summer it will) I will bring it back them for more investigating.

I have yet to attempt my own trans fluid work as I do not have the proper tool for the lower trans pan fitting. The diff may aid somewhat to the jerking with the OE bushings and fluid. As soon as I get time the new diff with poly bushings and better fluid will be installed in hopes to alleviate that jerking motion.

yeah it's as if the computer is re-adjusting the throttle and rpm. I get the same jerk sometimes.

Yeah that is pretty common design flaw of the 7AT, I drove brand new Infiniti Q50S, EX37 and G37 vehicles with the 7AT transmissiosn and they all do the same clunk occasionally, especially when you do a hard stop while simultaneously switching back to D ( Full Auto ). I drive these cars very often since they are all my customers car and I can confirm that. Nothing we can do about this. No TSB for reprogramming either. But so far it did no harms, just annoying, that's all.
