-OEM- Synthetic Automatic Transmission Fluid 88861800
-Royal Purple Synchromax
-RedLine D4 ATF
-Amsoil Synthetic ATF
-Amsoil 5-30W Synthetic Manual Synchromesh Transmission Fluid
First, why use ATF in a manual tranny? I am partial to Amsoil products, but really sorta stymied here on what to use. You guys have any observations or experience with this topic?
Appreciated any comments...

Tremec designed the T56 to have ATF used in it, and has had ATF in it for quite a while now. I have not looked into what the benefits are for ATF over conventional oil.
But as with a lot of things, people recommend what they use. If you are not in the severe duty category (road racing), the GM fluid is more than adequate. After that it just becomes your personal preference on which is better.
