Fact is the gear oils listed above for the primary have large sulfate additives, 10,000 miles or so - you will wonder why your stator is going bad.Â* 20/50 or 15/50 synthetics.

Thanks for reminding me of that. I still like using a gear oil for transmissions as they are designed for that application. Most of the gear oils supplied use inactive sulfates now. I had purchased lucas originally when I was going to switch and found this white paper about it. I returned it for something else after reading this, im trying to remember which brand i chose but it was something from this test I had bookmarked.
