West, for what it is worth I offer the following. I have a 1973 Datsun 240Z. The car had a noisy transmission and differential. This condition had persisted since the car was new, according to the previous owner's log. I drained and refilled the units with Red Line synthetic 85W-140 gear oil. This took care of almost all of the noise. I was impressed by the remarkable change. I don't know if this oil is compatiable with your transmission and overdrive, but thought you might like this information. I have a 115C and using an EP 85W-140 gear oil in its transmission and differential. This oil seems to be working just fine. John
