I believe and from the results now, pretty much know..that mine was leaking since I purchased it..the more I drove, and the harder I drove..the higher the quantity of fluid I would find under the front of the SVX..just the day before the failure, I had driven her on a 160 mile road trip to attend a funeral..while driving to said destination, which is on a canyon road..I noticed more smoke from under the car than ever before..everything remained fine until after the trip... I started it up in the morning and bam! huge fluid leak..the tranny was short 5 quarts..that made an impressive mess
