What are you putting it in?
That depends on the results of this poll sir. At the moment it’s whatever cheap stuff comes with the tranny flush, but I aim to remedy this behavior this time around.
I have used the synthetic oils produced by all 3 companies and never had any problems, it should be the same with the tranny fluids. I would choose the cheapest one.
I use Redline in all my diffs, MTs and ATs, but I have never heard anything bad about the other ones from anyone. Also, just to widen your choices, you could look into Neo fluids, which I have heard good things about: http://www.neosyntheticoil.com/
