I was trying to find a used one at my local parts yard but a 3.5 5spd tranny altima is hard to come by. I will throw back a few cold ones and stew about this, then start a real parts search tomorrow. Thanks again for the info, I could not find this on the net. Greatly appreciated.You're most welcome (although I'm sorry it wasn't better news). I don't think you'll have a lot of trouble finding a good used ECM, just be aware that you need to search using the JECS or Hitachi part number on the box and not the Nissan part number. There are also tons of places doing ECM reconditioning or exchange on those older units.
