As your pluto is tightly conjunct mercury, I feel this is more to do with communications,possibly 9th house matters, like your philosophies, religion, the law, travel etc. This is causing a T Square as T Uranus is square to saturn, trying to free up saturn’s rigidity. I call this one freedom v convention. It can work positively by incorporating new ideas, techniques into structures, or the other way around. Saturn is a true ‘wet blanket’ “This combination represents unrealistic standards of perfection that are unattainable. The result is increasing stratification of regulation and excessive procedure happiness. Pressure at work gradually builds up until release and collapse. It makes you feel uncertain, uneasy and insecure because the things that you count on for stability are no longer reliable. The chain of command in your workplace may shift significantly and there may be inconsistencies in the rules that seem hypocritical. Often this will be a source of tension between you and your superiors. It is not uncommon to change jobs or be fired at this time.2 http://www.astrology-x-files.com/transits/uranus-op-saturn.html
T Uranus opp Pluto is generational and in a cadent house, so you may not feel anything at all.
When I had this in late 7th ANGULAR house makes a big difference, I had major outbreaks and problems in marriage, even though pluto is well aspected natally and this was solar arcs not transits… never underestimate solar arcs.
