This might not apply but
Does anyone know when you have Transmission fluid gets on your driveway is there anyway you can get the stains out???
Try dry Portland Cement powder. It may take a while, but it will eventually pull it all out. Just sprinkle it on covering all stained areas and leave it set for several weeks. Clean it up and reapply until the stain is gone. If the stains are old it will take some time to remove. Good luck.
