I don't believe that these turbos will produce enough boost to need the OPV (Overboost Protection Valve). The ARV works with the vacuum transducer ("Blue Flying Saucer") to remove boost, and therefore provide smoother shifts. The entire system needs to be in perfect order for this to happen. Very rarely will you find an '84 or '85 with all that equipment working properly after 30+ years. It is my opinion that a transmission will last longer with firm shifts. The '83 and earlier trans modulator system had fewer components, and I try to make all the cars that I work on, employ the same minimal vac plumbing. With the EGR going, there is no need for any of that vac plumbing either.
