Brake fluid *will* "expand" the rubber stuff, - that's for sure. But like some of the products made for this purpose, - it has no idea when to *quit* "expanding" things. SO if you ever have to take that transmission apart, - you're in for the time of your life. Everything (with rubber in it, - which is a lot of stuff in an automatic transmission) will be (almost) permanently "seized". BT,DT.
