I took the van to the dealer today. They found the transmission case was leaking and will be removing and replacing it with a new unit. I guess they don't disassemble these things anymore... I'll be without the van for a week and have been provided with a loaner. I sure hope this is not a sign of things to come :s Only 1500 miles on it so far. They don't know what the cause is. I bought the van new with 320 demo miles on it.
