New one is in but it's not reading on dash neutral or drive. Please tell me what to do
nissan altima 2009What year/model? Virtually all Nissan CVT's require a data download of some sort to work properly. With a used trans I generally recommend that people get the TCM from the donor vehicle along with the tranny, that way you can skip all the programming. Depending on your model, you may need to visit the dealer to have them get an IP file for the trans out of the Nissan database, then download it to the TCM.
