I am having no issues with AMSOil's Synthetic GL4 Manual Trans fluid

jackstransmissions recommends the diaqueen. I tried it and noticed no improvement over redline mtl.

I don't think anyone is using the first one on your piece of paper, the Diamond Gear Lube.

Just to make sure this is cleared up...

The fluid Jackstransmissions sells is the Diamond Gear Lube GL-4, I confirmed with them. The Diaqueen(MZ313376/3717610 ) is not recommended for our trannys.

Doesn't change the fact that you didn't see any difference with the Diamond Lube though. I'm gonna give it a try and see how it goes.
