Hello, my trans on 2013 G37s has hickuped a feww times. 75,000 miles

I don't think I need it, but have the opportunity to buy a brand new trans for a really good deal.

But the seller says its for a coupe, and won't fit. I think they are wrong can anyone confirm this.? I imagine my mechanic may have to just swap some brackets, or maybe an rear housings from my old trans? Right? If even that.

 

100% plug and play.
