I don't know very much about import transmissions, and was wondering if there is anything inparticular I should be looking at. Could it be something like the manual valve being out of alignment and allowing fluid flow to try to engage a forward range as well as reverse when the shifter is put into reverse or neutral? I seem to remember something similar if you used the wrond "S" link in TH350's, but not being a trans specialist I could be mistaken. I have also heard mentioned a "lockout pin" that may cause this? Any of you trans gurus been inside these Nissan autos?
if your getting a bind or no movement in reverse or it moves forward in neutral, odds are that the forward clutches are metal to metal and seized.
depending on mileage, and how well the previous owner kept up with maintenance, or the lack there of, its very likely that the problem is internal and it will need to be rebuilt.
as far as the internal linkage goes, theres no extra link to hook up the manual valve, its a direct hookup.
