Thank's for your input Steven. I've been using a cardboard drip pad but just yesterday switched to an aluminum drip pan. Because of the location, it is almost impossible to see very much without the vehicle being on a lift or over a pit. I plan on taking the Van back to my Toyota dealer next week and leaving it for however long it takes to find and fix the problem. In the meantime I am keeping a close eye on fluid levels and the leak. :(
