Got my 2001 V70 back from the transmission shop after B4 servo replacement and flush with Type-IV fluid. Car is now driveable but still has intermittent flare going into 3d once the car is warm. I have used auto-rx successfully for engine sludge in Saabs (so I know it is not totally "snake oil") and recall that the manufacturer claims it also helps with transmission problems. I am thinking of trying it on my car's transmission. Anyone here used it on a transmission? Figure I don't have much to lose other than the cost of a bottle of the stuff (and my pride). How about lubeguard?
