its weird, they tested the head and said it was ok, oil temp never went above 104, pressure was at a constant 90(never went over) got no warning lights and it shifted like the shit off a shoval! now having looked at the oil and coolant they said the only thing that could cause such a mix would be the head !dodge but in my last vr the head was replaced(by the previous owner) because of the same symptoms and it turned out to be the oil cooler....
