I think the answer to this Dave is use the brake fluid with "moderation". What that means is just pour in a little bit, and wait to see what happens. If the leak persists may be add just a hair more, and I mean, a calibrated hair, here :) This is what I have tried to do over the past few years with my sedan. It seems to be working. The leak has slowed down, and the tranny still shifts just fine (I thought a while bac that the shifts had softened up, but that's not the case). Also, I think the "active" ingredient of the brake fluid is alcohol (please correct me if I am wrong). If that's correct, the stuff will gradually evaporate as the transmission gets hot, so its action will diminish with transmission useage, and will not keep on eating up the rubber, I hope.
