The manufacturer specifies engine oil. The question was, there is a reference from the PO that he used synthetic oil in the transmission. If he did, I would continue using synthetic, otherwise I would use the same oil that I use for the engine, Rotella 15W-40. Is there a simple way to determine if the transmissions contain synthetic or real oil?

Since it is virtually impossible to drain all the oil, I don't want to end up mixing synthetic and real oil.
