That transmission Nissan Remanufactured is about $3,200 then Installation. Expect that the technician will also want to put on a new radator and new transmission mount. You will also want to look into replacing any bad axles wheel bearings and CV joint boots. $5,000 out the door would not be to strange at the Nissan Dealership who will warranty there work one year. Or better yet limp that tired horse in and buy a new Maxima.
it can cost from 1500.00 to 3000.
