This weekend I used Amsoil 75W-90 GL4 lube, and frankly, I don't like it. Noticeably notchier shifting, harder to get into first, even with double clutching on a slow roll. The transmission IS much quieter at idle in neutral though, which is interesting...
I'll probably give it 1000 miles; if things haven't improved, I'm dumping it and going back to the Toyota fluid, price be damned.

Any mount/shifter modifications? What is your local temperature? Mines still been good all summer, but maybe I'll run into notchy-ness too as things cool down? Trying to figure out how we had opposite experiences.
Less sound would indicate to me less energy loss, and therefore typically better lubrication. However, that might make the synchros slower to react leading to more notchy feeling.
