Sounds like automatic transmission fluid ( If the transmission has been overfilled or has got water in it once the transmission is warmed up the fluid expands and can come out the vent tube ) or it can be a leak ( the transfer case for the AWD system and the Control Trac 4x4 system also has automatic transmission fluid inside it and the power steering system also uses automatic transmission fluid )
