Doing the figure 8s is mainly for new plates, these have been in service for some time, so they should be as free as they can get.

I don't believe Lubegard changes the lubricity of the oil so there shouldn't be any fear of it causing a problem. All I can say is that they are a reputable company and this problem has been remedied for myself and many others by using their product. For this issue, the additive cleans off whatever gunk gets built up on the various parts as a result of running the ATF too hot or too long or both. It also conditions seals, prolongs the useful life of the ATF and promotes wetting for better heat extraction and cooling of the hottest components. I believe LAN suggests Subaru ATF with Lubegard as a general practice. If I were running non-synthetic ATF, I would add Lubegard every time I added ATF. I see no drawback from him adding Lubegard to his fresh ATF. If it frees up whatever is stuck, great. If not, he will have better fluid in the tranny when whatever bad part is replaced.
