I'm pretty sure they are talking about the trany!
I would also like to know becuase I have a stock AODE on my 94 and wanted to add B&M ratchet shifter, transgo shift kit and a manual valve body. Is this a good idea, is it worth it on a stock trany? If I said something that doesn't make sense, feel free to correct me because I'm still new at this stuff even though I've had my stang for about a year.
