my hungry new stroker ! !

When I bought the truck I seen fluid all over the transmission and the transmission had been rebuilt 6 months previous and was still under warranty. I said if that's fluid all over the transmission we need to take it down to the tranny shop and see what they say. The previous owner and I went down there and the tranny shop looked at it and said that's oil from the motor. I assumed it was a massive rear seal leak..
but again not one drop on the ground and no smoke whatsoever and no codes being thrown by the computer like your following number a plug or something?
