Royal Purple Gear Oil

I just changed over to Royal Purple Synchromax last weekend it is supposed to be blended for applications where ATF is recommended. I think my tranny is a little quieter but it’s too early to recommend it. I am sure you are aware of the difference in opinion concerning ATF Vs Gear oil and I don’t want to open that can of worms again. I thought Synchromax might be a good middle road.
