the 708 its not capable of flashing any vehicles computer  there is no passthru built in  but if a new tcm its installed no flashing its needed  this module comes already flashed  if an update flash is needed then you need to get your self a passthru  a software call nissan nerds cost 270.00 dollars from nissan  and pay a sub 20 dollars per module  now if a new transmission was installed then adaptation is required the 708 can do it  let me know if i answered  your question  good luck.
