Hey Paul. I was reading the 85 Z31 brochure that I posted at 88hybrid and came across a statement that I thought was strange. The brochure says that the 85 NA used a different automatic transmission than the 85 turbo. Your web site said that "all automatic Z31s used the 4N71B transmission".
Is the confusion that both auto trannies that Nissan mentioned are the same tranny but set up different?
