Possible transmission issue?

Hello All!
I am looking into buying an 08 Rogue with 208000km on the clock but am getting a little worried about the possible transmission issues I know that plague this model. It drives fine currently but the current owner just had something fixed on it. They say it was simply electrical, but is this a quick fix to something more serious? See attached image for full description.
